Right now, Albertson's in AZ is selling Betty Crocker cake mix and frosting for .69 each if you buy 5. While I can't find any cake mix coupons, there are PLENTY of .50 frosting coupons in several different SmartSource coupon books, including the book from last Sunday (11/15).

Now, at the one I went to in Phoenix (51st & Cactus), the frosting coupon completely locked up the register. I think it had something to do with the fact that, currently, Albertson's is doubling coupons, and that .50 coupon is doubling to 1.00, but that COMPLETELY exceeds the .69 price. The store personnel eventually figure it out, but it resulted in my getting my entire order free, PLUS he gave me back a coupon (I had 5)!

Hope that helps.
