Living Social has a $20 Amazon gift card for $10! This deal is listed as being available for DC, but I'm seeing reports that anyone can snag it because it is a nationwide deal. This is limited to one per person and no gifting is allowed, according to the terms listed on the deal page. If you haven't joined Living Social, this is my referral link. I appreciate any referrals!
Go here to snag your $20 Amazon for just $10.
