Plum District customer? It is a daily deal website with the motto "For Moms. By Moms." Normally when you sign up you get a $5 sign-on bonus, but they are currently running a promotion in which you receive a $10 bonus if you go through a friend's referral link (mine ;). Even better, the friend who referred you gets $5 in Plum Dollars when you make your first purchase.
So go get your friends together and get your "referrrals" on!
