I like costcos more, just because I don't like wal-mart.
I chose Sam's Club. Costco's are nice, but you can get the same thing at Sam's Club, and SC memberships are cheaper.
how much is a sam's club membership? I know costco's is like $50...
I had both, kept the Costco.
Best meat, more up-scale selection than Sams and better prices.
The executive membership is $100 a year, but pays back a percentage of what you spend there, basically free or make money for me (YMMV).
