I think the price variations in AquaMax are likely due to transportation costs. Whether on a dedicated truck or via carrier shipping a 50 pound bag, or a pallet or truckload of them is expensive.

I bought 400 and 500 size last week at $23.95. My feed store is located about a mile from a Purina mill and I'd guess not much in shipping costs is built in.
