Buy Priority Club points for .6 cents each

View from the Wing shows how to buy Priority Club points at a fantastically low rate simply by reserving and canceling "cash and points" rooms.  This fantastic hack means that you can "buy" hotel reservations for as low as $30 (including tax).  Even at the high end, it can be a fantastic value.  I recently stayed at the Hotel Intercontinental in London for 40,000 points per night.  The room would have cost $700 per night otherwise, but you can use this trick to stay for only $240 per night!
