What People Are Saying: 5 Customer Reviews

  1. One of the better Costco locations with large parking spaces and ample room plus a gas station.

    Love shopping there, all products have good quality and reasonable prices. Come early is my recommendation

  2. This is my favorite Costco location in the area. Great customer service! Shout out to Dante who works and assists with the registers. He always greets and has a positive attitude. I can definitely tell that the staff enjoy working here. It makes the shopping experience much better!

  3. I personally love this location and it’s always nice and clean. Only thing I would like to see more of the lollipop lamb chops lol I’m serious though! Great staff

  4. One the better Costco I have been to. The food court area is always short staffed. The wait for🍕 pizza is long. In such a well ran store with all the employees they have on the floor I wonder if the labor market is that tight.

  5. Great service. We had a dead battery as we tried to go home. Even on a 87 degree summer day employees Camille and Johnny took extra time to give us a battery jump. We got home in plenty of time before the frozen purchases melted. Costco for the win!

    On Thursday July 13th, my daughter and I came in for gas. I did not have my membership card on my person. We decided to grocery shop since I knew that I could get a temporary card from the customer service desk. I asked my daughter to grab a cart, wait by the entrance while I obtained the temporary card. I was the only one in the membership queue. This was around 1630 hours, Ms. Nicole called for the next person, I walked to her register and did not get a greeting. I said “good afternoon” and received no acknowledgment from Ms. Nicole. Just a blank stare and a look of irritation. I told her that I forgot my card and wanted a temporary card. She said “ID” and I complied. I asked her how her day was going, she ignored me again. When she was done, she just handed my ID and the temporary card back and just stared. THIS WAS THE WORST INTERACTION I HAVE EVER GOTTEN AT THIS LOCATION. This was the opposite of customer service. I had to greet the employee, I had to try to make her feel welcome and I had to try to thank her for being there. Only the word “ID” was uttered by her during the whole interaction. I found Mrs. Aintonnette after my purchase and informed her of my horrible experience. The one star in this review is overly generous. Horrible experience. Huge turnoff.

    I am very disappointed with the service I have received today when going to pay for my things. The woman that supervises self checkout checked my card to see if it was mine, but it was my husband’s card but then in a very bad manner and very rudely tells me that I can’t pay because it was my husband’s card, when before I have used it so many times and she says they have started checking since 2 months ago but I went last week with my husband’s card and I had no problems. It’s ok if they tell me without giving an attitude but the employee sophiya was a very rude person and gave an attitude to me for no reason whatsoever. Instead of checking cards so closely they should focus on treating the clients with respect because they live because of the clients.

    Costco has always been a favourite place- it’s an emotion. This is another Costco, well- no this location DOES NOT HAVE GASOLINE! Otherwise, it’s super organised and well stocked store. You will find find good stuff in Costco in cheap price. Nobody can beat the price of Costco.

    Love this place! Cozy and a little art deco. It was my weekly happy hour spot. Until I realized my patronage was not appreciated. The drinks are great. The veggie platter is so delicious and fresh. Brussel sprouts are also good.

    Man do we love Costco day! And even though they were slammed with customers all of the associates were kind and able to help wherever needed. My daughter loves the samples and today we opted for the Ghirardelli minis which were absolutely a treat . Checkout was so fast I didn’t even realize I was done. Thank you!

    Best and quality items available in this place. All bakery items are very good and give long life. Just love the fruits and berries they keep. All are top one quality.

    Coming to membership better to buy gold for 120$ , worth it.

    At last, I just like to have their smoothies. I like both vanilla and strawberry flavours

    This location in Gaithersburg is always mobbed. But Costco is generally a great place to shop in bulk and my visit to the pharmacy was pleasant. They were helpful and tended to my needs. This location just needs to be relocated or have a better parking lot design.

Costco in Maryland: Do’s and Don’ts Every Shopper Should Know

When shopping at Costco, it is important to be aware of the rules and guidelines in place to ensure a smooth and efficient shopping experience. While Costco is known for its great deals and variety of products, there are a few rules that customers must abide by.

  • Costco membership is required: In order to shop at Costco, customers must have a valid membership. This membership allows access to the store and its exclusive products and services. There are different levels of membership available, each offering different benefits and perks.
  • No outside food or drink: Costco does not allow customers to bring in outside food or drink. This is to ensure the cleanliness and safety of the store, as well as to promote sales of their own food and beverage products.
  • No photography: Costco has a strict no photography policy inside their stores. This is to protect the privacy and security of their customers and employees. If you need to take a photo for a specific reason, it is best to ask a store employee for permission beforehand.
  • No returns on certain items: While Costco has a generous return policy on most items, there are a few exceptions. Electronics, such as TVs and computers, have a 90-day return window. Customized products, such as photo prints and engraved items, are also non-returnable.
  • No haggling or negotiating: Costco has fixed prices on its products and does not negotiate or haggle with customers. The prices are already discounted, and members enjoy savings in bulk purchases, so negotiating is not necessary.

While these rules are important to follow, it is equally important to be aware of the many benefits and advantages of shopping at Costco. With its competitive prices, high-quality products, and excellent customer service, Costco continues to be a popular choice among shoppers who value both savings and quality.
