What types of rewards sites exist exactly? I run one for online poker and I was thinking about expanding to other arenas. I have this one idea, and a domain - CashBackVIP.com - what type of rewards do you think I could offer? I was thinking maybe I could affiliate WalMart and other major retailers and give a portion of my sales % back to them in an account as "cashback" but I haven't read the TOC's to see if this is possible yet, I'd love to hear ideas
