In regards to the bulk oats at the store, while they are contaminated in the self serve containers because of the way they are handled, check to see if they have whole bag prices if you can use enough oats. Here, one of our bulk stores is Winco, and Bob's Red Mill is one of their suppliers. 2503 Regular Oats, 2504 Quick Oats, and 2514 Rolled oats are all BRM, and gluten free marked on the bag. Prices are about $35 for 20lb bag. And if anyone cares, 2105 all purpose flower is GF BRM for $42/25lb, or less than 3/4 the cost per pound of their 22oz packages.
