I didn't expect a simple Lantus refill to become such a seemingly impossible quest, but when I found myself delayed and unable to return home for another month, and then discovered that my pharmacy back home couldn't send me my insulin due to a "global shortage," Costco pharmacy came to the rescue. Luckily, the global shortage was exaggerated and this Costco did in fact have the pens in stock-- but getting my prescription transferred here so that it could be filled was truly a patience testing ordeal for the people here. Suzie could have given up. I wouldn't have known and if I had heard about it later I wouldn't have blamed her-- instead she made this happen. We are leaving with my Lantus, and a renewed appreciation of Costco culture and of the decency of one specific person and the dedication of the pharmacy. Thank you. read more

Came in looking for a bottle of Sintori whiskey and a bottle of red for a gift. We found the Suntori non vintage whiskey for $84.99, while they had the 12 year old for $144, i was ok to just get the regular whiskey. If you know anything about Japanese whiskey Suntori whiskey is an excellent choice for the orice with great value. Afterall i was visiting family and they never had a Japanese which before. This was a great opportunity to get a bottle at an excellent price. Also got a bottle of reserva Ribiera del Duero Montecrasto. As an avid wine drinker who loves Italian, french and Spaniard wines, the bottle was $23.99, really great value read more

This can't be an easy job working at Costco. Dealing with so many of these lunatic customers takes a special kind of person with a positive personality and exceptional way of dealing with even the most challenging customer. Hue and Heavenly in the Costco sign up department have that special thing. Actually the entire team has it. My buddy has been egging me on to sign up for some time. I had no reason why I did not other than I was lazy. I mean with the great prices, top shelf products, deals, and benefits who would not sign up. Is I preceded to head over to the counter to inquire on which membership to buy. After a brief wait Hue assisted me. He took the time to explain every single membership and its individual benefits and perks. Hue was extremely knowledgeable in everything about membership. He walked me through the best way to go for my needs and to be honest sold me on the Executive + and Citi card. It seemed to be the best fit for me and huge perks to go with it. All of which i will use. While Hue was showing me the ropes, an older heavyset woman I can only term a 'babushka' muscled her way into our conversation with a demanding question about someone helping her out with taking a picture. She demanded she needed her photo taken while invading our conversation and practically smooshing me against the counter. I wanted to tell her she may want to consider returning the several boxes of donuts she had in her cart as she didn't need more but her husband behind her holding the cart looked more beaten down more than she could have ever beaten on me. I opted to calmly tell her she needed to wait until I was done with my business. Which I must say is out of character for me, on any regular day I would have opted to let her have it, All during this Hue maintained his calm demeanor and continued with all the info I needed and running my card for an application and signing me up for Costco Executive. He managed all this while a few other errant customers milled around the service counter giving all the staff the evil eye. All I could do was make jokes and comment on how difficult it must be dealing with all these folks and it wasn't even a busy weekend. I would absolutely lose my mind. Aside of the extremely knowledgable and curious service Hue and Heavenly and all their team members provided to everyone around them, they possessed and extremely calm demeanor about them when dealing with at minimum extremely challenging customers. I have to say this store is huge and well appointed, extremely clean, and organized. I will likely make this my home store even coming from the northside of the city for a 30 minute trip. It's worth it. Hue was the actual reason I did sign up and apply for the Citi membership to begin with. With only a few questions had initially had for him he knew how to welcome me in as a new customer. Why would I not sign up with service like that? BIG SHOUT OUT to Hue and Heavenly for all their help, knowledge and exceptional customer service. See you all real soon! read more

This was the first CostCo I shopped at with my membership. This CostCo had a great selection. It looked like they typically have good produce here. The store was spacious, and they had a large parking lot. I enjoyed some mango slices I got at this CostCo. I was grateful for self checkout kiosks. read more

I love Costco! Great deals in bulk and free samples! Free bathrooms and parking and no bags wasted to kill the environment. You can take your stuff in a box you can upcycle. It's nice and warm in there too. And when there are sales, it's even a better deal. I have the best deal on seaweed that I've ever seen in any grocery store or Asian grocery. It's $11 for 10 packs of so much seaweed. read more

I had been texted an alert about a prescription, so, needing other items, I planned a trip to Costco. When I got to Pharmacy, a short blonde woman (Julie? Suzie! Dang, can't recall her name!) gently questioned me and shared that at the end of the text it said Rx would not be ready for two days, which I had totally missed. Instead of making me feel like a fool, she nicely suggested that I do more shopping and she'd have Rx ready in ten minutes. It was such a pleasant and caring conversation that I simply had to take the time to give this person 5 stars! (And a spot on Santa's Nice List!) The other Costco Pharmacy checkout folks have always been fine, but her warmth and thoughtful nature had to be commended! Thank you, young lady, for treating me with dignity and respect even though I was hasty and did not read the text reminder carefully. read more

This location has very rude staff, one in particular that is often at the entrance where you scan your cards. Both me and my husband are on the account and I carried his card instead of mine. The lady at the entrance was extremely rude un necessarily when she could have just asked me to get a temporary card from the membership desk in a more polite manner. read more

Costco is amazing! No what is not amazing, the parking lot at the Oak Brook Costco. People are very, very, impatient. From November through January be prepared to drive around for a spot. However, I will say that the staff here are patient and wonderful. I greatly enjoy the selection and quality of items. They have self checkout. Be prepared to show your ID when entering. As of 2024 they require scanning of card or app upon entry. Love costco! read more

I always enjoy someone greeting me at the front door at CostCo. As soon as I walked in I saw the highlighted deal of Body Armour Lyte and bought three cases. The sales they do have are always amazing on top of the discounted prices they have every day. read more

Review Title: Inconsistent Procedures and Rude Staff at Membership Desk 08/29/2025 -- I've been a loyal Costco shopper for over 11 years, but today was one of the most frustrating experiences I've ever had. I arrived at 8:53 AM needing a temporary membership card because I'd accidentally left my wallet at home after dropping my husband off at work. I had Apple Pay but don't have access to the digital membership card since I'm listed under my mother's executive account. I only needed a temporary card to get gas before a 9:30 AM appointment. When I walked in, I was stopped by an employee named Mhonia at the membership desk, who was unnecessarily rude and dismissive. Instead of simply directing me to the membership desk like what happened during a similar situation on 08/15/2025, she insisted I first "check in" with a person standing in the middle of the exit holding an iPad. Her tone and attitude were condescending, and it was clear from her smirk and demeanor that she was making assumptions about me based on my appearance. It felt humiliating and completely unnecessary. After "checking in," the iPad employee just sent me back to Muky at the membership desk anyway -- the same place I should have gone in the first place. Muky, by contrast, was professional, empathetic, and efficient. She provided me with a temporary card immediately and validated my frustration. I then spoke with Raul, the manager, to clarify the proper procedure moving forward. Shockingly, he couldn't confirm whether the process Mhonia insisted on was correct. He even admitted that the iPad employee could have printed the temporary card but didn't know how. This lack of consistency creates unnecessary stress for customers and allows certain employees to exercise power in a way that feels degrading. If there is a new procedure, Costco should clearly communicate it to both customers and staff. Because of this confusion, I wasn't able to finish pumping gas until 9:22 AM -- nearly 30 minutes after I arrived. I want to recognize Muky at the membership desk and James at the fueling station for their kindness and professionalism. They salvaged what was otherwise a very upsetting experience. Costco needs to train staff better, ensure procedures are uniform, and hold employees accountable when they treat customers with disrespect. Muky demonstrated better customer service skills than the manager and deserves recognition. read more

Everything about the store is awesome. I am always satisfied and the help I get couldn't be better.

I haven't been in this particular Costco in quite a while. One thing that hasn't changed is they have one of the biggest, busiest, and congested Costco parking lots around. With their great Oakbrook location, they are always very busy and they have a huge customer base. I also noticed something today that seemed different and that is they offer a ton of samples here! I thought the Glenview location was the champion of Costco sampling, but this place is in a tie now I think, yeah! read more

To me this is one of the largest Costco's close to Chicago that I know of and frequent when I am near. I was shopping for a new OLED and decided to stop in. I had help from the employee to decide and he helped me load the flat bed and gave me all the paperwork I need to support the TV in case of defects. Once outside at my car they even helped me load the car up and the customer service here was impressive. I did not even have to ask and they offered. You can't go wrong with any TV here and it comes with 5yr warranty $99 value included in the price. (no brainer). The parking lot is huge which can be intimating but well worth the walk into the store. read more

I have been a Costco customer for years. I drive a car that takes premium gasoline so gas from Costco is a MUST! Great high-quality 93% octane (not 92 like at Thornton's) at the best gas price anywhere. read more

Amazing customer service!!!I was at this location on Friday and bought a whole bunch of things ... one of the items was Burt's bees chapsticks pack. When I got home to chicago realized it was missing. Immediately I called Costco and was connected to Nikki in customer service, she said bring your Receipt and we will get you a new one. I of course didn't believe it would be so straightforward. Sure enough Monday morning I walked in. And Chris at customer service said he can help and he opened a book and saw a note from Nikki . It was easy because of how organized they run the store. Thanks for helping me out! read more

Costco - Costco gas... lines at all Times !!! - Wholesale Stores Near Me - Oak Brook, Illinois

Love Costco! This one is located in Oak Brook. Like others it's pretty busy and the parking lot can be a cluster. Inside on busy days, people are constantly running into one another. The gas station outside is adjacent to the parking lot, so traffic can be a nightmare. The store is well-stocked and pretty clean. Love their frozen salmon burgers the best. read more

Costco - Wholesale Stores Near Me - Oak Brook, Illinois

As a longtime Costco member that visits a lot of different Costco's I can say that the store has room for improvement. The parking situation is usually hard to find a spot in prime evening/weekends, there is usually a line at the food court, and the staff is not as friendly as other locations when it comes to assisting the customer. With that being said, it is still Costco and they do have great value, but given the option, I prefer to shop at other Costco's due to the numerous less than ideal interactions at this location read more

This place has the absolute worst traffic flow of any Costco I've ever been to. It was clearly built to adapt to the space vs the space to adapt to the store. Gas prices are always a bit higher however because it's in a higher end area they tend to get higher end one-off luxury products like Patagonia, etc. Standard costco, remember to pack your patience before making a journey! read more

Costco isn't perfect by any means, but still deserves 5 stars. I know I will get quality when I shop here and their return policy is great. Also gas prices are great. Parking is crazy here and it's always so packed but the cashiers are super efficient. read more

The self checkout doesn't supply scanners (Sam's does) so usually an employee will scan your waters, toilet paper etc. the heavier items but today the Costco employee stood at the end of the registers and stared into space...nevertheless to say I had to pick up my heavy stuff....grrrrrr....then I had to process my card twice because the machine refused it. After two minutes I did it again and my card was accepted. Bye Costco! read more

Stick by when a product says 2 year warranty and u don't approve of it stick by it I went into Costco asked for store credit or a refund and I had a 2 year warranty and they didn't take it don't even look at the warranty because they don't care about it read more

Complete ZOO - almost anytime throughout the year, especially between October thru December. Parking Lot - ZOO (seems to only be a one light/one area in and out of the place, too). Store - ZOO. Find another Costco to go to, if you are able unless you enjoy shopping with enormous crowds. read more

Costco has the best prices for lenses. It's 50-50 if you get a good customer service representative. I lucked out and got Alejandra. She is wonderful, kind, knowledgeable and professional Ask for her it will make your lens/frame buying experience pretty great. read more

I do not know what is going on with Costco lately. I bought Good Foods guacamole at the North Riverside Costco. It comes in a 3 pack. The packaging on the outside does not have an expiration date. It is on the inside plastic clear tub. I did not see the expiration date until I opened it at home. There is no way I can finish 3 tubs of guacamole that quickly. I called Costco North Riverside and they said I had to bring it back. I told them they should probably check the dates on the rest of the supply of guacamole in the store. I hope they did. I called corporate Costco and they said I could just bring in my receipt and get a refund. I did not trust that, so I headed out to Costco again with the product in hand. I ended up at the Oak Brook Costco instead because I had to get to work. It was closer to by employment. I brought it in and the girl was quite rude to me. I said I called first and she gave me the refund, but I did not appreciate the attitude. I was kind and yet I was the one that was put out and purchased an item that was going to expire in 2 days. If you have a warehouse club and sell in bulk, the dates should be monitored closely. I have been paying for a Costco membership for 11 years. I had an executive membership for the first few years, now I have the regular membership. I do not appreciate being disrespected for returning food that will expire in 2 days, when I pay for a membership and groceries are very expensive these days, plus I was treated like I did something wrong for returning it. I called corporate again and they said to go back and talk to a manager. My only reason for the calls were to make them aware so things could be looked into. Checking the dates better and having their employees be more courteous. I guess Costco is well established and makes enough money now, that they can just do whatever they feel like doing with out needing any input from their customers. Pretty sad. I also have been asking and writing suggestions for a year now to please bring back their Quinoa salad that they use to make in their freshly made prepared section. They have not once responded to me or even acknowledged my request. As a customer, I feel quite dismissed. Time to reevaluate if I should continue my membership. By the responses and lack of responses, I get the feeling they could care less what I do. Also, I agree with the other reviews, the parking lot at the Oak Brook Costco is a nightmare. read more

I will not be returning to this location and business. They were not helpful nor pleasant. I bought a Groupon membership, had the information and confirmation number, yet they would not accept it. I only wanted this for shopping with my special needs residents but they were not accommodating whatsoever. I have reached out to Groupon, and they say that the issue is with Costco and then vice versa. This was a very, very unpleasant visit. read more

Simply the best soft serve you'll ever have. I got the twist vanilla and chocolate, in a 16 ounce cup for $1.99. It's a must try.

Love the bulk options and the free samples. Could almost get a whole meal out of how many they set up! Always packed no matter when I go though. read more

I've been a Costco member for only a short time and I love this place more than the Orland Park location and the Bedford Park location. Costco is nothing but an emporium of treasures. Parking was really easy to find, enjoyed browsing around the store mindlessly for over an hour. Got some good. They have alot more on their menu then usual on what they offer. This place also sells cigarettes in a little closed off area that looks hard to get too like Fort Knox with its security cages. They also have an area where they have a local artist selling his paintings. That was really great. I love the staff and the people that shop here are really generous too. If I ever stop in the area more I'll definitely be back. Thanks Costco read more

Costco - Ginger Beer - Wholesale Stores Near Me - Oak Brook, Illinois

Costco your big box buy all bulk products even if you don't need that much. You can pick up some great deals at Costco, but a lot of the items are not that cheap. This store in Oakbrook must be a goldmine. The parking lot is enormous and any time of the day you come here it's packed. Like all Costco's there are some items that are such a great value they are hard to pass on, things like the hot dog for $1.50 with a drink, both chock full of nutrition. (NOT) Their rotisserie chicken for $4.99 is like 2 or 3 meals for me and the wife. I never clean the carcass completely as I use the bones to make my chicken, ginger, garlic soup. After boiling and simmering the chicken for my soup base I scoop out the carcass and set it aside to cool off. Mince a ton of ginger and some garlic along with Vegeta let simmer for another hour or so and add the chicken cleaned off the carcass & add Noodles or barley & ta da the soup is done (better then the soup Nazi on Seinfeld) and Oh so easy to make. Gas is also a great value usually 20-25 cents less per gallon. The other thing that I really love is the Costco Executive Card which at $120 (just increased from $110) is a bit pricey, but the perks coupled with the Citi Costco Card can be many, earning anything from 4% to 1% on purchases. Last year we earned $364. When it came to redeeming the points I purchase about $67 dollars of merchandise and got back $297 dollars cash HOW SWEET IS THAT? read more

Super rude staff. Called twice asking about a product because the price was different here and another store, then I told that I just needed to see if they can see the promotion like the other store can so I can make sure the deal was in the Chicago land area, was met with sass and rude ass remarks like "well doesn't matter what the price is because we don't have it right? Right." Excuse me? Doesn't matter if yall had it or not what if I just wanted to know the price? Wouldn't recommend coming here. This isn't even the first incident. It's like they love NOT doing the bare minimum for people who pay for the damn membership. read more

Horribly dirty place. Workers are unhelpful and the parking lot is a mess. Not one worker came to help a woman when her child vomited at the checkout. Nobody cleaned it up just the poor mother, and all she had was paper towels read more

The service was horrible. When we were getting the receipt checked and mark, we saw an old man in his 70-80's and he said that he was here to pick up his subscriptions for his health because he forgot it. The staff said he was not allowed into the pharmacy because they were closed (it closed 3 minutes ago) staff was really against him but us and 1 worker helped his get his medication but we don't know if he got it or not. Then my husband was inside the Costco getting a phone from T mobile. He still had to shop around but he had no money for him and we were waiting outside. We tried getting in because it JUST closed. They said we were not allowed into because it was closed. But we did not stand there because he still needed to get the stuff he needed for Costco. Service is terrible and will not help their customer's no matter the age or situation. Completely disrespectful staff hopefully the old man got him medication read more

My least favorite Costco. I love the deals, and the parking here was plentiful and easy. Other than that, staff is unhelpful and cranky. You'll also find the customer's cranky too. Is this a chicken and egg scenario, staff is cranky because of customers or is it the other way around? I stopped in because I was in the area to check it out, and like usual can find something I need. However, now if in the area I'll stop in if I know I definately need to pick up something and it can't wait until I get back to my south loop location. read more

Do not recommend. At all other Costco locations when you use self checkout, you do not have to wait in the line at the exit. Here, the worker requires you to wait in the long line and argues with customers. She also does not speak fluent English which is a problem when you are going to be dealing with customers. read more

I like this store. It's huge, clean and easy to find stuff. Best to go during the week to beat the crowds. If you must go during the weekend, go early unless you enjoy the crowd and the free samples, ymmmm. They have more organic foods than Sam's Club. I'd go back! read more

Costco has gone worse in customer service. Today (03/07 @ 5 pm CST) my wife was buying grocery and she spent 1 hr picking up products. After all the shopping she was refused at billing just because I could not be there with her. They could have let us know that next time she cannot shop without the member. She spoke to manager and supervisor, they did not listen for a minute and were very firm. This is so ridiculous, given that I am hearing this for the first time, We could have received a FYI and not to shop without the member. However the un-customer service would not let us do that. I am not saying that this right, but they could have let her shop given that we are hearing this for the first time. In my household sometimes I go for shopping or my wife or daughter, given this absurd policy we cannot ever shop in costco. Being customer with Costco for 12 years, I am totally disappointed and frustrated with this kind of treatment. read more

Yes the parking lot can be a pain to navigate but short of that.. I always have a great experience at this costo. Notability their selection in clothes and flowers. I've bought a desk from there, printer, you name it. They have the best selection every time I go in and I'm never disappointed. Notably I wanted to write a review on their optical department. I went in a month ago and got a pair of contact lenses to trial out until my new set of contact lenses came in. I have astigmatism and I rarely find my prescription at a store unless I order online. Well I ripped my last contact lens before my new order came in. I have glasses, which I also got from Costco, but with the mask and me not being used to wearing them all day, I was worried how long I'd have to wear the glasses in the meantime. I called and came in and got a new trial contact lens to hold me over in the meantime. The receptionist even said if they don't work me her and the Dr can figure something else out. What a peach. I am so grateful for them being understanding and helpful. They're always busy I promise, it is worth the wait time. You will be taken care of. read more

I think this is the best Costco in the area when it comes to overall variety offered, which is strange as it's a smaller store. They're the only location that we know of that still has a (very tiny) section of craft beer bombers, which unfortunately has been axed from the Naperville location which we usually shop at. The parking lot is a battle royale free for all, but that's true of every Costco. Go on a Saturday at around 2:00 in the afternoon and you'll basically get lunch for free thanks to it being all hands on deck when it comes to having the sample stations set up everywhere. Just beware, sampling inevitably leads to you saying, "Damn this is really good," and ... hundreds of dollars later you're leaving the store with meat balls, cheesecakes, cookies, and all sorts of other things when all you originally planned on was a quick trip to get another bottle of vitamins. read more
