Is Costco Open on Sunday?
Absolutely. In fact, for many members, their favorite time to shop is on Sunday afternoons. The after-church crowds come through anxious to try-out the many free samples lining the aisles. In fact, there are typically so many samples available on Sundays that many have coined it the “Senior Buffet.” The samples are expansive and delicious. You can fill up your belly and then add your favorites to your shopping cart to take home with you. Everyone loves free food!
Consider stopping by for a snack (or a full lunch) this Sunday. If the samples don’t fill you up, try out their signature soda and hotdog combo for just $1.50. Word on the street is that “Sunday at Costco” is a delicious experience, you don’t want to miss.
Members can escort up to two nonmembers at a time, but only members can purchase goods. The club’s store brand is Kirkland, which also happens to be many members’ favorite brand to purchase. Kirkland is inexpensive and of great quality. An ideal match! (Check out our Costco price list to compare prices.)
