David,
The sanctioning body is trying to help the sanctioning body, and the supplier, as they sold the fuel supply rights to the supplier. The sanctioning body is getting their money. "If" there was a stipulation in the contract that regulates what the supplier can charge, that could help the racers, but there may not be, and the sanctioning body can just stand back and shrug their shoulders as they deposit the checks from the supplier. Your business and their business are different. You wanted competition and availability in your supply chain, because you needed the materials, and wanted them at the best prices. The sanctioning body is selling naming rights, and supply rights, for supplies they are not buying. It is a totally different business.
