This is one of the easiest Facebook coupons I've seen. Just become a fan of Planters “Mr. Peanut”, click on “get coupon” and print. Print 2!!
Also on Facebook, a coupon for a FREE package of “Mega Mystery Gum.” Become a fan. Click on the Mega Mystery tab, then click on the big pack of gum. Confirm your age and give them your mailing info and your done. ***Note: it's being reported that IE users are having trouble accessing the coupon. You may need to use Firefox.
If you don't have a Facebook account yet, you should consider signing-up. It's worth it just to get the coupons. You don't have to set it up as a social network. You can just create an account to get the coupons. It's easy to keep it private.
