Fly for Free Thanks to the U.S. Mint

The dollar coin trick involves purchasing large amounts of coins with a frequent flier card, waiting for the Mint to ship the coins (free shipping!), and then taking the coins to the bank, where they are deposited and the money is used to pay the credit card charges. No money is lost, the frequent flier miles rack up, and travelers can use them for upgrades or completely free flights whenever they want.

Apparently this trick still works but it is limited to $1000 3 times a month, but 3000 flier miles a month still is not bad. I don't see this working for much longer, but hey get 'em while you can right?
