We have a membership at Costco, which if it lapses they "automatically" renew when you next buy something.
They always want my card AND drivers license, so lots of luck using somebody else's.
Sams day pass works great for me, they do them several times a year, and no surcharge in Calif. I like the Seville Classics clone of metro wire racks, and Sams and Costco carry different versions, and I like model Sams has a bit better than the Costco.
What sucks for me is we used to have a warehouse outlet store here for costco returns and open box stuff, and it just went all wholesale, no retail. My last purchase a pair of UGG type boots for my son for 50 cents.
