most gas stations started charging an extra 10 cents per gallon if you pay with a CC when gas hit $4 a gal. saying they were being charged more since the total sale price was higher.

Or say 2 1/2%, well some figured it still paid to use a CC if getting Double Miles or Pts.

Be careful as the price of gas is falling (paid $3.71 last night in NJ with a CC others same price Ca$h only) the % is going up, as they still charge an extra 10 cents per gallon at $3.71 meaning you pay $3.81, that they charged when it was $4.19. So as the price of gas goes down the % that the 10 cents represents goes up, so as the price per gallon gets closer to $3 it gets closer to a 3% fee for using a CC.
