Free frequent flier miles (or other stuff) ?

Now I guess I missed this opportunity.  The US Mint was lots of 250 $1 coins with free shipping.  The story goes that some people racked up to $800,000 in coins which were all promptly taken to the bank and deposited and then used to pay off the credit card.  This amounts to 800,000 miles.

I would have used it to get $8,000 in rewards of some other sort (like money).
