Good question...years ago you could buy travelers' checks from AAA using any credit card and they would be charged as a purchase...easy to see what you could do with THAT deal Unfortunately, the genius that milked it the most (got MILLIONS of miles by having his whole family spend many a weekend at AAA counter-signing checks), went on Dateline NBC to tell everyone of his personal perk...didnt take long at all that AAA was told to drop that right away. Now you can only use a AAA issued card for the same purpose...no perks there. If anyone knows of a credit card or debit card (without max/year mile restrictions) that can be used to buy money orders, travelers' checks, etc. that would be very interesting news. Most of the stuff in other posts refers to debit cards that give 1/2 mile for purchases (no cash/negotiables allowed) with annual mileage caps...the savings bond deal is going away with the new holding period limits and Citibank locked down their cash-transfer program to prevent mileage "abuse" (as they called it). I think it is hard to find such a card, unless you find one overseas that has looser rules and is denominated in USD.
