While Sheetz has some interesting flavors (banana) for their specialty drinks, I feel the options are too few. The other night I wanted a cinnamon hot chocolate more than anything and assumed sheetz would be able to fulfill my desires only to be let down. I think some flavors that would be great to include would be: Cinnamon, coconut, toffee nut, dulce de leche, and orange.
