Geo;
Understandable, however the reason I made my statement is most convenience marts in my area seem to have a statement posted by the register minimum C-Card purchase of $5.00 required. Anything less than that amount they expect cash. Above $5.00 they have no extra charge for the card, same price as cash. Most of them have their own company card for the brand of fuel they carry, but accept all major cards as well.
