EDIT: It looks like all the coupons have been printed.
CVS and Coupons.com have teamed up to offer a coupon for one free Hershey's Air Delight Aerated milk chocolate bar. But here's a little secret. You can print the coupon twice by hitting your browser's back button after the first one prints. That's 200% more free chocolate than you currently have and it comes with free air!
This offer has made my day. Don't ever let it be said that I'm not a man of simple pleasures.
