There are new coupons at coupons.com that would work tomorrow only (8/3) at the Kroger Mega Event. They have added .55 off 1 Betty Crocker frosting and .50 off 1 Betty Crocker Cookie Mixes.
When both of those double and are included with other participating products (you need 10 products total), they'll be free! You should be able to print both coupons twice and more if you have more than one computer! Remember these will only be good on Sunday!
