My credit card agreement states I am to get 3% rebate for my gasoline purchases. My bill reflects only a small portion of my gas purchases were recognized for this credit. On inquiry to American Express, they stated that my purchase of "automated fuel disp" by ASTRO (a gas company) would not be credited with this rebate "because the company's original registration with American Express did not state they were a gas station".
The only other sales by this place are cigarettes (my family and I don't smoke).
