I have one refferal already Five more would be awesome!! Depends on what prize you choose, the number of credits or refferals is different. I choose $250 paypal, which requires either 7 credits or one credit and 6 refferals. You get to choose!! Some offers are partial credits, so watch for the ones that give one full credit!

Pick your choice of prize- $100 to $1000 paypal or gift!! Get one refferal for $100, 5 for $200, and it goes on (27 refferals for $1000!!) You need to complete only one offer and get your refferals to complete only one offer also! I'm going for the $200!!
So you see here, I'm aiming for a total of $950 for just a few minutes of doing offers and getting refferals! You can too!! It's not really difficult. People are doing offers, getting refferals, and then getting paid in one day!! There are some offers that are free to do, but the majority ask you to pay for a trial subscription. I highly reccomend doing the Tickle offers!! There are a few for $4.95, $9.95, and $12.95. Those come with a 7 day trial, which will renew for $19.95 monthly if you do not cancel during the trial period. Just think that the reward outweighs the initial cost!!
BTW, there are many many many other sites that offer other prizes other than cold hard cash! Just check out http://www.mommyjobs.com/boards/index.php and go to the Autosurf, HYIP's, Pay to Read, Survey's, Etc. folder!!
