I guess it’s been more than a month now since I started receiving these so called PayPal Wishlist invitations. I really don’t know how this thing completely works but I know about this rule that when you refer your friends to use this or if your friends accept your invitation to use this, you will earn 1 dollar. That means, 1 dollar is equal to each friend referred. I haven’t tried it but my friend says it’s true. I don’t know. I still ignored all their invitations. I don’t want to risk things out. :)
