We don't have a Costco that is convenient to us. My wife used to share a membership with her mom, but we found we almost never went so it wasn't really worth it to us. There was a BJ's nearby but it closed. Not long after that it was converted to a "Costco", but only as a movie set (for a terrible Ben Stiller movie). People were so disappointed when they found out it wasn't going to be a real Costco. It's now an indoor go-cart track.
