I honestly like the shopping experience at Costco -- there aren't a million variants of the same thing to choose from, you find really good deals sometimes (on already good prices), they have new random and sometimes good things all the time (I'll sometimes spontaneously buy, then confirm with my wife at home and if not, return on our next trip), and my kids go to the food court and enjoy the pizza and hot dogs that are decent quality and low priced. We go every ~2 weeks.
