If you go to the area to get a SUPERCERTIFICATE from Giftcertificates.com, you can then get a 50.00 Marriott certificate for "only" 5500 miles. It used to be 4500 but they changed in several months ago if I recall.

Of course the better value is to wait for a 100.00 certificate for 9000 miles, but we will be too old to use the certificates by then or milesource will be long gone.
