That's all fine - businesses can be within their right to do whatever they please. However, myself and myriad of other people will simply go elsewhere where we are not charged different for the same product/service depending on the method of payment we choose :)
I stopped needing gas long time ago but if I needed gas I sure as heck am not going anywhere where I can save $0.10 to pay in cash (probably spend 2x that in gas needed to get to the gas station to save $0.10 per gallon). or for that matter ain't going to any place that has a different price depending on my method of payment.
I was also going to say, between the Costco executive membership's 2% rebate, and CC incentives, it's probably a wash anyways between that or the 10ยข difference.
