Costco is a members‑only warehouse selling a huge variety of items including bulk groceries, electronics and more. The Frederick location is busy all the time, tight crowds, extremely long lines and the insanely packed parking lot from opening to closing. The warehouse is well‑stocked, well organized and the staff is helpful and courteous. Costco has a great return policy and a Gold Star membership. Customers appreciate that the warehouse is always busy and crowded, sometimes out of Kirkland Vitamin water but better stocked recently. Customers wish later weekend hours.
Got gas...no line, so I pulled right up to the pump. Lowest price I paid in the last week!

Costco Wholesale:
Great offers and products that I like, during the week the place is easy to navigate but during the weekends gets a little busy. Download the costco app for an easy way to know the latest deals. The staff is always friendly and ready to help.
