RARELY are there ever coupons for milk (maybe because it’s a government subsidized food?) but check this out: http://promotions.whymilk.com/ggg/
If you enter the Why Milk contest to win free milk for a year, the first 125,000 entrants get a coupon for free half-gallon of chocolate milk with the purchase of 2 gallons regular white milk.
Thanks to my pal Heidi @ Little People Wealth for this great tip.
PS: Hurry! This deal is undoubtedly going to go fast.
