This Walmart has a dedicated gluten free section with many options. They also have a frozen food section that is gf. They carry many gluten free options at a cheaper price than most grocery chains.
Pleasantly surprised during a recent trip to find out that Walmart had a small dedicated GF freezer section with Udi's and Glutino products (pastas, English muffins). Also had snack products on a GF shelf (pretzels, cookies, mixes, etc). All was reasonably priced.
