There are a few ways to accomplish this, first way is like Maxell said, sign up for an account at a payment processor like 2CO, slap together a shitty website like youre selling something (better use something that doesnt involve physical delivery of products, like ebooks/software, cell phone unlocking codes, long distance minutes, etc, you get the idea)
and then buy from yourself.
Another way would be to become an affiliate of something that accepts PayPal as payment, and offers a high commission (75% or more), then buy the product (once again, better to stick to non-physical goods here), and you get the affiliates commission.
I really don't get this process. So you are basically saying to buy a product from yourself. For instance if the products costs $100 you would get $75 as a commision which means that you lost $25. What am I missing here? Thanks.
So why would anyone go spend $100 to get $75?!!
I can see this work only if you really wanted that product and then you buy it yourself and spend only $25 instead of $100. Also it would work with pay per sign up or free trial products but those 99% don't pay paypal. So for example you would spend $5 for a trial product but you would get a $20 commision, so you made $15 on this transaction. But they don't pay through paypal directly but at the end of the month so you run into a high risk of gettting caught. I don't know you say that I am not missing a step but it seems to me that I am since why the heck would anyone want to lose $100 in order to make $75?!
