Folks, make note that this is awesome coupon is for the TRAVEL CENTERS, not the food marts. Usually the Pilot Travel Centers have diesel for big rigs, and the signs specifically say Travel Center on them. Become a Facebook Fan of Pilot, and look for the “coupons” tab to have access to this coupon, valid through May 23. Note that you do not have to purchase anything in order to redeem the coupon, but who doesn’t need to fill up their gas tanks??
