Thanks I do find myself earning more gas/diesel than I can use, so it is handy that you can set an Alternate ID code (10 digit I think) via your on-line account profile which can be keyed into the pump keypad to access your discount w/o need for FuelRewards card itself. This can be shared with select friends/family who know to get the whole 20g (bring gas cans if you have to!) and not burn a 2.40 discount on a purchase of 6g.
