11/07/2009 The outside sign shows regular unleaded gas 87 $2.66. As I was fueling I noticed on the pump the price was $2.73. I stopped fueling went inside to let the cashier know the pump was wrong. She told me that if you pay by credit or debit card it is 7 cents more a gallon than if you pay by cash. Is this legal? I have NEVER seen this before.
