I love this story about collectors of frequent flier miles gaming the system. The US Mint was selling dollar coins (at face value, of course) with free shipping. So these mile collectors realized that they could charge these on their cards, get them shipped, and use the money to pay their credit card. Free miles! But this guy is the best. He claims to have bought $800,000 in frequent flier miles, and he’s got photographs of himself taking delivery of enormous sums of these coins.
Every so often these sort of incentive programs develop a loophole, and I just can’t get enough of stories of people who consequently buy hundreds of cases of yogurt or pay for nights in hotels that they don’t stay in.
