to get points?

I dont have Discover card to use in Sam's club..so I buy a walmart gift certificate with my credit card which gives me points for all purchases, then use it at Sam's.
I need to buy another walmart card now....any ideas where I can get points for buying walmart card?

not much profit buying on ebay as most gift certs on ebay go for a dollar less than the value

thanks for your advice in advance


also, can I post other freebie sites here?
