Just thought I'd FYI. I was in a local feed store and happen to notice NutriSource has been doing some formula tweeking and is now going Wheat-free (most likely due to the expense of wheat, but IMHO it's still a nice touch). So, for folks looking for a more affordable wheat-free alternative, it might be a good food to try. If you do try it, make sure the bag has the "Wheat-free" or "No Wheat" sticker as there are still bags of the "old" formula still on shelves yet.
I do caution those that have severe wheat-family sensitivities though, it does still contain Barley.
