Costco Wholesale 880 Russell Avenue, Gaithersburg, MD 20879

"Very busy, as usual for this Costco. The lines go very fast. I was dropping off my elderly passenger close to the entrance. Before we could get the car door open, a greeter appeared with a cart and a smile!"

"Sometimes we go 20 minutes further to the Frederick Costco instead of Gaithersburg because of definitely being the worst parking lot even before construction and the busiest. Organization of lines for food service and checkout is always a problem at Costco but since this place is so busy all the time you tend to see a verbal fight or two every time you go. Sometimes entertaining."

"Staff are not friendly and they don't want to be fair with you. I got a Mikasa set and found a broken bowl inside. I went to the store the next day, they told me since they don't have any sets in the store at that moment, I can't get any replacement and I have to go to Costco in Frederick, which is more than 30min drive away, to return the whole set and get a new set. How am I supposed to fit everything back to the box and safely transport them to Frederick? I've been shopping at Costco for more than 4 years and I always loved it. I'm Very disappointed at the staff at this location."

"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."

"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."
