  • They have recently introduced a new line of organic products. Great value and quality. Try to go during the week. Weekends can be crowded.
  • Eat before you fill up your cart with enough useless supplies to last through the zombie apocalypse. $1.50 for a jumbo hotdog and a cup of Coke is a good start.
  • Best Costco ever! You can get in and out in no time. Great parking and very helpful staff!
  • Duh...a warehouse filled to the brim with major savings on products. Great for stocking up on toilet paper, toothpaste, feminine products, or whatever. Fabulous to shop here in preparation for winter.
  • Say hey to Tiny at the door
  • I <3 Costco in Frederick! If you use the self check out, you will be out the door in 15 minutes or less!
  • Once you come here you will never want to go back to the one in Gaithersburg.
  • Love this location. Not too many people. The best customer service ever...
  • Self checkout is the best way to check out
  • Combo pizza is the best
  • The hot dog is a cheap meal!
  • Go get your eyes checked
  • Love Costco .... Just wish they had a scan & Go app like Sams Club. Who likes waiting in lines?
  • You do not need a Costco membership to use their pharmacy. They always have the right medicines in stock. The staff is great. They remember your name and they are mostly fast to fill. Not open Sundays
  • The lines can get long with even longer waits at the Pharmacy and sick people try to cut in line -- sad.
  • Free air for your tire and the mechanics will repair the tire too!
  • Whats not to like. Although I do wish their food sizes were better for two people.
  • Self checkouts are great!!!
  • Folks often drive up from the more urban local Costco's as this place is much less crowded and hectic than closer in stores. Good for me I live here.
  • The free samples!
