instaGC.com 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 monthly offer and referral contests as well.
I really like InstaGC and it really works! I hope you guys can create an account and join me :O)
