We're considering getting a Costco membership with the deal that was posted on the boards today. We would probably only shop for household goods there (toilet paper, paper towels, trash bags, etc). Are the prices on these items really worth it?

The closest one to us is about 30 minutes away, but if we only went a couple of times a month and made a trip out of it (like ate lunch there in the super cheap food court area) then I don't think it would be too bad.

What sorts of household goods do you buy at Costco?
