I know of a few… One in particular I really like is www.cashcowarcade.com

They offer “cow points” and you can exchange it for real money or items… Kinda cool! One thing you can do with your “cow points” is buy scratch cards…. My very first one was worth $10. I was sooo happy!!! LOL

Any others out there????? What site do you like?
