My tractor dealer sells some total products now, and he can sell them at reasonable prices. He used to carry Chevron but he wasn't able to offer it at a reasonable price.
Ultramar gas stations carry total too as they are owned by the same group, and I imagine ultramar is pretty competitive on its oil prices as well, so probably more bulk customers will pick it up.
I suspect up here, that retail sales are a much smaller percentage of the market compared to bulk buyers.
