Ok, Here is the deal... I have not tried this, I just saw this and thought it is interesting! At a glance, the owner of this video has made it look complicated. I mean the process for anyone getting a free gift card does not seem like a simple click of the computer mouse.
That does not mean it is impossible though. I think you can make some money too, but there is work to be done, just trying to get referrals can be quite a handful of work. Good luck
ah! the site he is talking about is here yourgiftcards4free.com
if you wish to check it XD
