Gas prices are reasonable. Gas attendances are very courteous. It is so convenient to shop at Costco and then go for gas in the same location. read more

Not the cheapest gas around!! Complete BS!! The BP station on eastbound lane just before you get to Costco is same or cheaper without having to wait on line. I noticed same thing in Lawrenceville NJ area. Live that Costco perceived value and the only benefactor is Costco. Big lines always. Nice employees because the are Costco full benefit employees so that may make the purchase of gas here of value to some. I don't think they even scan or require your Costco membership card so I don't see it worthwhile not to Patronize local gas stations that are reasonable and have been serving you, unless you live in Bedminster, where they rip you off! read more

This costco is a pleasure to go. The store is well maintained and always looks clean. The products they sell are always quality which they stand behind. The people working there are always helpful and friendly. read more

One of the cleanest and fastest Costco in the central NJ area (Union, Edison, Bridgewater). The register is set in a way where it's not blocked and lines build up. I've never gone on a weekday or weekend where the lines are outrageous like at Edison. There is gas as well liquor store. The liquor store, unlike Edison, is a private 3rd party that's housed in the warehouse but is technically "outside" of the warehouse. You don't need membership to purchase, but you enjoy the Costco prices. They DO NOT carry Kirkland branded liquor however, just name brands. Prices are comparable to other Costco. read more

This Costco has a huge parking lot and its needed on weekends. Gas Lines are Very Long on weekends as well. Get your gas here as less expensive than anywhere else, but go on weekdays, especially not busy in the morning. Shopping here I would also recommend weekday mornings and afternoons if possible. Prices & selection are typical Costco. Tire center is also not as busy weekday mornings and afternoons. If buy tires, be sure to get them when on sale. They rotate the brands of tires on sale over and over again, so just wait until the ones you want go on sale. Overall, I like this Costco better than Edison or Bridgewater. read more

This Costco, unlike others in NJ, seem to have the most experiences workers keeping the store neat and clean. The cashiers are amazing! The work together, are polite, and actually put a smile on your face. I gave up my Costco membership because I could not stand the store and it's clientele. This one has changed my mind. read more

Nice and convenient location. Well maintained so far. I appreciated it when they helped us dry the cart in rainy or snowy days. I got tired of their practice, however, of checking my membership at the entrance. I can't buy anything without the card; so why bother to check it at the entrance! read more

Love Costco .I go there for everything PLUS the Gas. They take VISA CC only ..no more AMEX.

This is the best Costco ever!!! The employees are all super nice and helpful and the store is never overly crowded during the week. I absolutely LOVE this store!!! read more

Cheapest gas...on an average at least 10 to 12 cents less per gallon when compared to other gas stations. No Cash, just Debit and Visa. Usually long lines but worth the savings. read more

The best Costco in the area. It's very clean, they always have what I need and I can get in and out very quickly if we go at the right time. The staff is very friendly and helpful and the check out lines move quickly. I always look for Shaun C when I'm getting into line. He's super friendly and very efficient. I'm my opinion he's the best employee at that store. read more

We favor this Costco because the lines are always manageable and people aren't hitting me with their shopping carts. As with any Costco, the choices vary but they tend to have most of what we need. The people who work there are very helpful and will go out of their way to find something for you. This Costco has a decent selection of bread, pastries, cakes, and prepared food from which to choose. read more

I have been to 5 costcos in my lifetime and this is by far the best. Plenty of parking and less crowded than any other i have ever been to. Also has a liquor place in house. read more

Your standard Costco shop. Costco is just great, in general. When getting gas, you'l have to step out to enter your pin number and then the gas attendant will fill it for you. read more

What a great costco! Clean, empty and the staff is so courtious. Like a breath of fresh air compared to the Westbury, NY Costco I usually frequent. We even enjoyed lots of free samples of goodies! read more

Go on the weekdays it's less crowded. They have 12 pumps doesn't matter what side your gas cap is on cause the hoses extend to reach. I use premium gas it's the cheapest by far! Attendants are always friendly. No Costco card needed just debit or AmEx No cash! read more

Its new, its clean, its costco. If you're used to the Edison and bridgewater locations, then take note you might get a little disoriented when you shop since the floor plan layout is different. read more

This place is really good the prices and the quality of the products. This place is well kept and organized which makes easy to buy and shop there. read more

I went there for an emergency tire replacement at almost closing time on a Saturday. I was so impressed with the professional, courteous, and helpful staff! Ray Conor & Ricardo worked well past closing time to get me on the road again, while never giving me the feeling that I was putting them out by keeping them late. I will be going back very soon to replace the other 3 tires on my car. I thank them all and highly recommend this business! read more

Clean, spacious store with courteous and helpful employee's.....and you can't beat anywhere their all beef jumbo (¼ lb) hot dogs for $1.50 including unlimited soda's.... only downside is when you buy AND LIKE an item, there's a chance it won't be there the next time you shop....they change seasonally, and that's good.....but sometimes favorite items won't be there when you look forward to buying them......disappointing.....their liquor store, which I believe is not a Costco's property, prices are on the high side compared to other liquor stores. ..otherwise this Costco is a very good shopping experience. read more

THIS REVIEW IS FOR THE GAS LINES ONLY! I used to love coming to this store to shop for the family and to fill up with gas. None of this is easy anymore. Because the price of gas is so low here ($1.69/regular today) there was about an hour long wait to get to the pump. Now I'm just estimating but the lines from every direction in the parking lot were more than 2x as long as they were the day I had to wait 20 minutes to get to the pumps. The lines are in fact now causing problems for the people just trying to get a parking space to shop and also for those who just want to leave the parking lot. There has to be something that COSTCO can do to alleviate these issues. read more

I love shopping at the No Plainfield Costco. Everyone is very friendly and helpful. They get You in and out without long lines. The samples are great and the food court is cheap. read more

How can you not love the Costco in North Plainfield? The selection is tremendous, the staff is always pleasant and helpful, and nothing beats their return policy. They are my go-to place for many items. read more

Always find what I need here plus they have a gas station and wine store on property.

Love this Costco, great variety of produce selection and the gas always has the best price!
