Tasha , Superior customer service!
Robin M.

My husband and I just had the BEST experience from the Optical department from an associate by the name of TASHA .We thought she was the Manager !. My husband was only going to purchase 1 pair of glasses ,he end up buying 2 pair! She took her time explaining and listening to all my husband questions and concerns and making sure the center of his vision was centered and marked the glasses for pickup . NOW that is ***** Customer service. Friendly and Knowledgeable consumers ask for Tasha . She the Best That made his birthday in which is today!

This salmon was pre-seasoned with cooking instructions, just remove the lid and pop in the oven: totally recommended. Came out very good!

It's so funny how when a lady asked me to apply for an executive club membership, I said "no" because I don't come here that often. I've been coming here a lot more and more than what I said to the lady when I first applied for membership years ago. I really love that there is a Costco close to me. This Costco has great selection of items and I always get what I need. The one con about going to Costco is everything is big. What I mean is if I need just a carton of milk it comes in a pack of three. But the price is right. Costco always has great holiday items. Costumer service is ok. I rarely need to ask for help. Unless I go to Optical or their foodcourt area and then when you check out. That's the only real reaction with employees at Costco.

I booked an appointment to have my tires replaced. When arrival, just park on the tire space for customers. The staff got my information and provided an estimate of 1 hour and 15 mins. My wife and I shopped around to kill time for a bit. When we were at the register, the lady scanned my membership and told us we are eligible for a 2% discount since we moved to Oakley. We just need to update our address at the membership counter. I was really surprised and didn't knew at all. After everything was done in about an hour, we waiting at the tire shop. One of the staff came and said the car was ready which was pretty quick than the estimated time. What I liked was how the staff done an amazing job explaining everything in detail.

So as friends, family and Co-Workers (Yeah I am talking about you) will attest we have a obsession with Costco. So much so we have a set of Costco Rules we live by (after the review). This is your typical Costco and it flows in a clockwise direction from the entrance. You have your typical array of electronics and season items int he front and center and work you way back to the meat and freezer sections As I stated in my review of the the Mountain View location, we do have some rules to help keep our obsession under control: 1) NEVER EVER go in hungry. That 25 gallons of dill pickle chips is much easier to resist on a full stomach.... true story there. 2) Avoid the free samples. People seem to lose their minds with this stuff. They abandon carts with crying babies, block isles, etc all to get that tiny portion of hummus. I have been shoved aside by someone desperate to get a free piece of cheese. Honestly I have seen more dignity from actual starving people in a disaster zone but I digress. 3) Avoid the weekends like the plague. 4) See #1 5) Go often. Costco uses alot of psychology and the fear of missing out is one of them. Odd items you must have pop up then go never to return. I CAN'T MISS OUT AGGGGGGG 6) Know your codes: At costco any price ending in 0.97 means it has been marked down. Any price that is not a 0.99 or .97 such as say 0.49 means it has a manufacturers discount. and price with an * aka "The Death Star" on it means its done and will not be reordered so stock up. If it ends in a .00 or a 0.88 a manager has reduced the price at that location to clear it out. 7) When in an unfamiliar city head to the Costco. They always stock local items you can't find at yours (like two pounds of single origin Kona coffee for 30.00 at the Kilaua / Kona store etc.) and have cheap gas. (Same on Kauai)

And Hot Dog

I really only come to COSTCO for the food. If you are short on money, or trying to get a quick bite, this is the spot. You don't need their membership in order to eat at their food court. COSTCO is well known for that hot dog value: $1.50 for a hot dog AND a drink! You could never beat that. Pizza is $1.99, and the slice is generous and delicious. I do have a membership I had been given, but I don't shop here because it's not worth it for me. In my opinion, COSTCO is great to buy in bundles. Perfect for families and numerous people for a long time. Since I live alone, I don't need to purchase these bundles, that are naturally more expensive But COSTCO is a winner, and it always stay busy. The one here in Pittsburg is full of deals, with electronics, glasses and numerous things to look at. Parking is big, so you'll be okay to at least get a spot

Wow do those sample givers know their stuff. We were looking for granola bars and she totally…read morepointed us in the right direction. Then she gave us a hint that if we didn't find the kind we were looking for near the nut section to try the cereal section. We looked at the bars next to the nut section and they didn't have the exact bars we were looking for. There were bars, but not what we had in mind. Then we went to the cereal section and there they were. Last time we got the Natural Valley in the green box. We're on box number to so it's time to mix is up. This time I got the biscuits filled with almond butter. I had one this morning for breakfast and it totally hit the spot. My next quest was toilet paper. Thankfully it's locate in the same place as the Sacramento store, in the back on the left hand side of the store. They now have a extra soft Costco brand ones. I got the old stand buy in the blue package for the lower price. i find it adequate so why spend more money. Pineapples were only $2 each a total steal. The only downfall is they all appeared over ripe so we passed. Too bad and that may explain the great deal In the clothing section they had World Cup Jerseys for under $10. That is if you wanted the Argentina jersey. They had USA jackets, buy those were only slightly under $30, too much for my taste. I would have gotten Argentina one, but they were out of size small. In the Lego section they had a Messi Lego set. How fun would that be! In the tomato section they had over 5 varieties. My dad loves snacking on tomatoes so he got the snack size the cherry tomatoes. He said they have more flavor than any of the other varieties.

We were in the neighborhood, and I needed to fill up my car's tank. My wife also wanted to return…read moretwo pairs of pants she had bought that didn't fit right, and I was looking for a shirt I had seen at our local Costco, but they didn't have it in my size. So, after getting gas, we decided to check out the warehouse. As it turned out, this is one of the better Costco locations I've visited. It seemed bigger than our San Francisco location, and I found the shelves and merchandise to be well organized. I quickly found the shirt I wanted in the right size, and while my wife was doing her thing, I walked around and browsed the aisles. Although I wasn't looking for shoes, I came across a pair of Ben Sherman sneakers on sale. The reduced price was so good that I couldn't resist. I tried them on; they fit, and I ended up buying them!

Otherwise 2 stars is my personal experience from multiple visits in the recent months, especially from trying to get there in time for Pokemon random drops throughout the day. I seem to always miss it, with Focused Fighters and with Ascended Heroes ETB + Pokeball 2 pack. I wish they did a raffle system where they give out raffle tickets to everyone interested for 1 hour, and then at the end of the hour they call out the raffle numbers. Essentially an in person version of the Walmart online raffle system would be nice. Their selection of items seem to be not as diverse as Costco's is too. For example peanut butter, they have a hydrogenated version and then one with added oil, no "natural" one for their Members Mark version. No sugar free jam. Their milk section didn't have organic almond milk or lactose free milk just regular milk. Lacking a lot of personalization type of items. I know you could say "just go to Costco then" but that's not my point. My point is, they can do better, and it shows I expect more of them. I mean even Costco's Pokemon ticketing system makes sense and Sam's can't do it for some reason. Pricing though is hard to beat overall, for everything. Thus my personal 2 stars. Don't let this review affect how you shop here, this is just my personal experiences here with at least 5 visits the last month.
