I don't usually buy frozen pizza because we make our own, but when there is a good sale, I'll pick one up to use in a bind -- this keeps us from needing to order out on those busy nights!
Through Thursday, Acme has Red Baron pizza on sale for $3 each. Pair it with a $1 off coupon (from the Jan 23 Smart Source) and it came to just $2. BONUS! On the back of some of the Red Baron boxes were coupons for 6 free wings at Buffalo Wild Wings (with the purchase of 12).
You cannot use it on their wings night specials, but its a nice discount, and the coupon is good through the end of June!
