Started doing PR myself, made some pretty decent giftcards from Amazon...
Then I found SimpleGPT, pretty much the same thing as PR, except the offers you complete are actually for CASH, which in turn you can WITHDRAWAL INSTANTLY via Paypal!
New offers are added daily, plus they have great weekly contests, and the same types of bonuses for referring your friends, just like PR!
ok, i'll bite. Please pm me more comprehensive information - for instance, how much time and how much work is required for someone to get a $5 gift card
