Kellogg's Cereal for $1 a box!

This week, Kellogg's cereal is on sale for 3/$6.  There's an in-store coupon for $3/3 boxes, taking your total to $3/3!  -$1 a box!  You can NOT stack any other coupons with this deal though, because the in-store coupon is NOT a DG store coupon (it has the new barcode on it, so it looks kind of funny, but it's a manu coupon), it's a manufacturer coupon.
