As you have all probably seen this type of thing on ebay b4 there is no point in me trying to explain how this thing works, but believe me if your willing to spend £7.99 you two can get a PS3! This is what i did:
When you sign up you have the usual complete one of your "sponcers offers" i looked through them all and i went for the "Rent DVD's for Only £1.99" by easycinema, when u sign up to that you have to pay a one off payment of £7.99 for your 1st 4 dvd rentals, then if u want to keep on using the service u just deposit some more money, they don't take it out automatically, so after your 1st 4 dvds u can simply stop using the site. My 1st dvd came within 2 days after i signed up.
However, there are other offers to choose from so its up to you which you get.
Then once you've done that its just a matter of getting your friends and family to sign up, or do what I and many others do by using eBay.
Anyways i hope you decide to give it a go, and thanks for taking the time to look at this.http://gaming.freepay.com/?r=35848569
