For a few years, the Shell station on the corner gives you a few cents discount if you come inside to pay with the credit card. I've always thought was a bit shady so I rarely go there.
There was a story on the news about using debit cards...some banks will put a hold of more than the purchase price until they figure out how much you actually paid...don't ask me to elaborate, I don't remember the specifics, lol.
First time I've ever filled up my Altima for $60
