The site suggested does work...On one hand though, only use the cpa button and not the ascendmedia button because the ascendmedia button doesn't work. I've done this a few times so that I would have a code or two to giveaway, so I know it works and so do the people who have gotten a code from me, although you do run out of easy options either way, I'd say if you haven't tried it you should. You can get a good 7 or 8 codes before you run out of easy surveys.
