Can I Pay Cash?

Can you pay cash and get a discount instead of paying with a card? So when working with private individuals, sometimes ask yourself the question, can i pay cash? Cash often, in the right circumstance, speaks louder than the plastic does. I would love it if all stores offered cash discounts. But until they do, why not look out for yourself? Could you pay with a credit card instead of a devot card in order to get better consumer protection? Any time you're buying electronics, or or something like that consider paying for those services with something like an american express or some kind of platinum.
