there doesn't seem to be a retail box option, just a downloadable purchase. Call me stingy but I prefer physical media for something that's well over $100.
I looked in the FAQ and didn't see anything on the subject, I also called the support line and after several attempts each one ended with a message saying all lines were busy then I'm disconnected each time...
I would gladly buy the boxed version on amazon, but the upgrade price is way cheaper and the current offer of plugins is very enticing.
