Amazon Lets Users Send Gift Cards Via Wall Posts, which Recipients Must Redeem through Facebook

Amazon has launched a new Facebook integration which allows users to send gift cards to a friend’s wall. It is also running a promotion where users get $5 in free MP3s in exchange for sending gift cards (minimum value of $1) to five Facebook friends. The promotions generate leads for retailers both direct and indirectly, and require users to give Amazon access to their social graph in order to redeem their cards.
