It's $.003 per mile. I'm surprised at the responses to this thread. Go to your LOCAL stores that sell MOs and ask, or buy a candy bar and Try It. And it does not have to be a Am EX. My LOCAL store that took Am EX stopped it, but I still have 2 stores that take MC and Visa and treat it as a purchase, and have for the last 3 years. I'll ask again, anybody want to fess up???

Think small and think consistent.
