You have to place the order, but the Garmin rep told me they won't
charge you until they ship.

The other issue I have is the initial demand will be very high, so
expect to be without your box for a couple months or more. How will I
be compensated for my aircraft down-time whilst my 530 is off at Garmin?

Did Garmin promise an eventual upgrade to WAAS when you bought your 530?
