I have the very same Question. I tried to get to my account, but I was told that my email was incorrect, yet I could get into my account with the forum url I had when I started with the 90 day trial. The cost was half for everything but the workbooks. I have decided that I want to buy the apps and the books, but I am having a heck of a time trying to even get onto/into my own account. BTW, I checked in my account to see if I had made a typo either on the account here or on my email account password to get into my account in the first place. Both of my fields the same, and they are accurate.
Please contact me via my email so I can buy your products, or I'll have to restart my Adobe account again.
