Anybody out there know anyone in the Shell, Chevron, etc... marketing department? Now that fuel is upwards of $3. 80, pay-at-the-pump credit card purchases only get me 2/3's of a tank. Amex says its the seller, Shell says its Amex. I say Shell could increase their revenues by 50% (to me) by increasing their credit card limits to match their increased fuel prices. You know, "one good turn deserves another".
