Got it.
The document itself is short, only 1 page pdf, and for the most part clear however I did have to read it twice to ensure I understood what was going on correctly.
I have not and will not be attempting this myself (I use paypal for a lot of things and would rather not risk it) but after reading it I do believe it would work, but I doubt it could be repeated much and would instead have to be done only a few times or maybe even only once.
As mentioned by d4rkwizard in order to make money you must be willing to put in money of your own to get the ball rolling.
Ultimately if it does indeed work (which d4rkwizard says he confirmed) you would have no problem earning back the $10 you invest to purchase the guide itself.
