Better/cheaper- Costco or Sam's?

[JEDI]

i have a costo membership. just wondering if it's worth my time to get one those free Sam's memberships?

what advantages of costco over sam's and vice versa?

 

[Farbio]

i don't think there are really any advantages of one over the other, although costco does have gas, so that's a good thing, but as far as one cheaper than the other, its negligible. sometimes one will have better selection on stuff than the other, but it changes so one isn't better than the other necessarily

some Sam's Club have gas by me. I'd say whichever is more convient is better.
