Odds are, they are talking about a feed store, but buying it in 20 pound bags. And they did say that some weeks would be more than five bucks, others less. The $5/wk is an average.

I'm not sure when this list was produced. Either that, or we're getting hosed on food and feed costs around here. I was in a feed store a few weeks ago, and it would cost a bit more than five cents a pound right now for wheat. For any kind of feed grain.
