Free Target Gift Card from Plum District
New offer from Plum District -- refer 3 friends and receive a FREE $20 Target Gift Card! No purchase is necessary.
Just click on "Get It" in the purple and green ribbon, and the site will walk you through referring your friends. They just need to register and confirm their email address. I recommend referring people through Facebook because they also need to sign up using Facebook Connect.
Get started here.
A few months ago, when they last had this promotion, I received the gift card as promised!
