If you ask my oldest daughter what one of her favorite things to do is, she'll unabashadly tell you, "Go to Costco!" It's mostly about the samples for her (I mean, isn't it for everyone?), but we also do the bulk of our grocery shopping there. (No pun intended.) Which means we end up at Costco almost once a week. And we usually go as a family. It's kind of a thing.
