I would be interested to see the response from businesses about this. It almost makes me wonder if a company would make more money by giving an incentive for paying cash. And with the holiday season just around the corner I could see some places doing just that -- pay cash and get an additional X% discount. I think on major purchases (computers, t.v., appliances, etc.) using a CC is the best way to go as it protects you if something goes wrong. But on smaller stuff (toys, DVDs, music CDs, etc.) a small discount to the cash payer could be beneficial to the vendor.
