I use swagbucks for amazon gift cards and I know a lot of members do. I also do this other site called InstaGC where you can cash out for unlimited instant gift cards. I also get amazon codes from them. Today I stumbled across an off to get 2% back in InstaGC points when you make a purchase on amazon. So you can make more money for amazon codes when you spend the ones you already have. Its a super easy site and if you guys would like to check it out I would love the referral. http://www.instagc.com/users/join/23522
If you are looking for the amazon offer once you get to the site on the main offer wall page type amazon in the keyword box.
