Raptr's giving away 35%-60% off discounts on Logitech G-series peripherals as part of its new Raptr Rewards system. I work at Raptr so full disclosure there, but I think this deal is something that many people would be legitimately interested in.
You have to have played at least one of a long list of very popular games to qualify, which most people probably have. It's pretty simple: Play games, earn rewards!
Feel free to drop a reply if you have any questions!
