Hurry and print this coupon before it’s gone! The $1.00/2 coupon for M&M’s, Dove, Snickers, Twix, Milky Way or 3 Musketeers candy is valid on packages, two ounces or larger. Since the theater boxes of M&M’s are 3.4 ounces, they work. I bought two boxes of M&M's at Walmart for $1.00 each. I used the $1.00 coupon and paid just $0.50 per box!
