This contest looks great! You can win a year supply (one free gallon per week) of milk by entering the contest at Why Milk. There will be 120 winners. The first 125,000 to sign up will also get a free milk with purchase coupon (I got a free half gallon of chocolate milk with the purchase of two gallons white milk, but there are a few others you may end up with).
It ends on Feb 8th and you can enter daily, thanks Smart Couponing 🙂
