If you're looking for a grain-free food, try Taste of the Wild. For the price, it's totally awesome. I know around here it's about $10 for a 5-6lb bag, and that can last a little dog over a month. You'd be surprised where you can find some of these foods... if you go to their website, and type in your zip code, they will tell you the closest stores. Alot of hardware stores carry it, or Tractor Supply. Ace Hardware surprisingly carries some decent brands as well. Here ya go...
Taste of the Wild : Dealer Locator There was like 6 or 7 locations that came up in Arkansas.
As far as food sold at Petco, I would agree Natural Balance is probably decently priced. If you have a Costco near you, I often hear great things about Kirkland and apparently it's really cheap for the quality. Whole Earth Farms is another brand that is always having great deals, and is really cheap. petfooddirect.com currently has free shipping on Merrick (Whole Earth farms) products, and 20 percent off as well.
