Deal Pulp's deal of the day is a great one if you haven't signed up for a Deal Pulp account yet. If you sign up now, you'll get a $3 credit AND if you refer another person before the deal is over you'll get a $3 credit for that referral as well!
Some of you may be wondering if it is worth signing up or not. I always figure that I might as well sign up when daily deal sites have these promotions because I never know when I'll be able to snag a bargain with my credit. In other words, it sure can't hurt anything! And it has paid off for me- I've gotten several great buys as a result.
