This is what their terms said:
The price is valid for a full 12 months. After that, we'll renew your contract automatically, at the then-current price of the offering, unless you cancel. The price is subject to change, but we will always notify you beforehand.
Setting this black friday sale aside, the normal price for the package is $49.99. I'm fully expecting to be auto-upgraded from $9.99 to $49.99. Whoo Hoo! (sarcasim!)
So, I figure this is a 1 year trial to play with CS and I'll be canceling and returning to purchased Lightroom when the introductory offer (my words) is up.
I suppose the "then current price" could be $9.99 or $11.99, but I doubt it!
