I wanted to make this thread as an aggregate source of tricks to earning bonus miles. I always seem to find out about them too late to get in on the free miles, and I'm sick and tired of that.
For example, several months ago, the US Treasury was selling $1 coins at face value with free shipping. Hundreds of customers purchased the coins on a credit card earning free miles, then deposited the coins in their bank and paid off their credit card bill. BOOM! Free miles!!! Link
