Free $20 Target Gift Card

Plum District is a newer daily deal site (well, new compared to say, Groupon). They have a pretty cool promo going on today. If you refer friends & 4 of them sign up (they don't have to buy anything!) you will receive a $20 Target gift card!

I haven't purchased anything from Plum District yet, but this seems like a nice way to become familiar with them.
