My question is whether the membership cost makes it cost effective. Assuming that one lives in such a fashion as to use only limited quantaties of things at a time and has limited storage space (now that I think of it, neither of these apply to you, Taztik), it seems like there are a great many things you can't buy at Costco. For instance, I use maybe a head of romaine once every two weeks. If I buy a pack with three, they will go bad before I use them.

I never had a costco card in SF, but I'll be living scant blocks away from one in NYC. It just seems silly to have a bucket of something that will take me a year to finish when I don't have the space to store even the essentials.
