Can you carry Mormans? Not sure if that is a conflict with Purina, but they have good show feed also. We feed Morman's pig feed to the two show pigs we raise every year for our local county fair, and at $40/cwt, it is NOT CHEAP!
I strongly suggest you get in tight with the local FFA and 4-H groups, support the local fairs and such. Our feed store will buy our kids premium, or make an "ad-on" if the price goes too high (usually the kids make about $300 total). It is great advertising for the business to put a little back into the kids pockets. We buy feed at that feed store because we know they support the kids at the county fair. It benefits both of us!
