cash only for cheaper gas.

this place never fails to have the cheapest gas in Irving period it averages anywhere from 5 to 10 cents lower than the other gas stations in irving

A typical convience store gas station.

This gas station DOES NOT accept the gas buddy card. There is NO pay at the pump option. Although they do have the cheapest gas in the area. The attendant was very nice when I asked about why tho.
