I have Vegas 5 and DVDA 2 - CDs and manuals. If I sell these on Ebay, can someone buying them from me turn around and use the serial number to get the $149.99 upgrade price for Vegas 8 (I used the Vegas 5 serial numbers when I upgraded to Vegas 6, and plan on using the Vegas 6 serial number to upgrade to Vegas 8). I don't want to mislead anyone if that is not an option.
