Anything you find at Walmart isn't going to be a high quality food. Iams, Pedigree, Beneful, etc.
I would check out
Pet Food Supplies Dog Cat Bird ... PetFoodDirect.com. I've never purchased from them, but I know they have coupons all the time, so you can sign up for their mailing list. (email)
Food I'd recommend are Orijen, Innova EVO & Wellness CORE. If there is a PETCO near your area, I believe they are now carrying Wellness products.
Hope that helps.
