I bought this out of curiousity more than anything else.  After reviewing it I realized I am highly qualified to give a review on the method because it's what I do but in a much safer manner and have a few thousand transactions already completed with them.

To me I wasted money. 

To everyone else, yes you can make money from this if you use throwaway accounts when spending your gift cards.  The main problem you are going to have from using this technique is most of the cards are carded or stolen.  You aren't the one that carded them or stole them but a big chunk of what you will get are just that.  Sometimes you'll get lucky and you won't have any issues for a couple of months, then all of a sudden everything will pile up on you and you will be hit with a tidal wave of chargebacks and unauthorized transactions.

If you used a bank account you will owe them money.  If you used online accounts at different merchants they will shut your accounts down.  The method he is teaching is not safe at all if you're looking for clean money.

On that note if you know how to cover your tracks or just don't care... you can definitely make money with this.  Buyer beware.  This is definitely not a method that everyone will want to use.
