PetSmart has a BOGO sale on Purina Bella dry food and a B2G2 on the wet; use the $3 dry food coupon and the BOGO wet food coupon, both in 3/12 S and pay pretty much tax. I bought 8 bags of dry and 16 wet and paid $3.11, almost all high tax.
There are also printables: $3 off Bella dry food and BOGO Bella Filet Mignon plus BOGO Bella Beef in Savory Juices plus BOGO Bella Grilled Chicken Flavor plus BOGO Bella Porterhouse Steak.
