Possible Betty Crocker Coupon

Found this coupon through an ad on my yahoo mail page. I don't know if this link will work to print the coupon because i've never done it this way before! That said it is a .50/? (it didn't say just that it was .50 off) i'm assuming two, boxes of Betty Crocker Patatoe au Gratin. Let me know if this one works guys, i'm not around a printer so i'm sorry I can't tell you more about the coupon. If it doesn't work keep trying your homepage for yahoo mail, maybe you'll get lucky!!
