[url=http://www.instagc.com/369008]instaGC.com[/url] was created in February 2011 and is the top rewards site that offers instant gift cards to its members. Over 100 different options are available (example of a few -> Amazon, eBay, League of Legends, Pizza Hut, Target, Walmart) that you can redeem your points for. Tons of easy offers available with new ones added daily. There are daily, weekly, and monthy offer and referral contests as well.
This site is the best gift card site that i have seen so far. I have gotten xbox gift cards in a matter of days. And you can get several other gift cards within a couple of days. Give it a try :D
