I just ordered the upgrade:
"Microsoft Visual Studio .NET Enterprise Architect 2003 Upgrade from 2002"
From Amazon.com for only $ 28.60 including shipping (well shipping is free)
The reason I got it for 28.60 instead of the normal price of 29.00 was because they have those earn a nickel questions down the page a little. Answer each question and you get a nickel.

Anyway, I thought I would tell you that you can get it from Amazon.com cheaper than you can get it from MS. Also, MS says they are backordered now until the 19th of May... Amazon says it will ship in 2-3 days. Hopefully that is the case.
