|This is an auction site like e-Bay, only difference is everything is 100% free! If you list something it has to be 100% free and anything you win has to be 100% free.|
You can get free credits by selling stuff, which I sell a lot of free codes I get online, or you can try out the offers. (Ex: Netflix is worth 10,000 credits)
I currently get $20-$30 amazon credit from this site every week. Prices have seemed to have jumped since I first joined a couple months back. $1 amazon credit is going for ~1,000 credits. I save up for the larger auctions now and get a $5-$20 cards for ~800 points per $1.
You get 500 points free at sign up if nothing else you can get some cheap xbox live avatar codes.
