For the past few years we have heard a lot of news headlines around gas prices. They go up, and they go down. When you get gas, you have a choice of paying with cash or credit. Generally speaking credit is about 10 cents more than cash per gallon. It is estimated that about 15% of all gas purchases are with cash, 85% is credit. The 10 cents is supposed to absorb the credit card transaction fees, but is it? If you go to an Exxon/Mobile station and use an Exxon/Mobile card you get the cash price. Shell stations have a similar deal. Other cards will offer an incentive of 5% cash back. So do the gas companies really need to charge the extra 10 cents to make up for the credit cards fees? Is 85% of the public just paying an extra 10 cents for no reason? If Exxon and Shell can eliminate the transaction fees cant others? Each year in the US 140 Billion gallons of gas are bought, that 10 cents adds up to a lot of money!
