I purchased the Flex Builder upgrade today from the Adobe Online Store. When I went to find the serial number for my download, I was presented by a 'Contact Customer Service'.
So I contacted Adobe's Customer Service, and they said it would take 24 hours to provide me with a serial number. You may not want to purchase this from Adobe until this gets worked out in their online store.
According to Matt Chotin, all of the serial number issues have been resolved with the online store, so it should be safe to buy online.
