Sounds like a good deal. It doesn't have to be a boxed version; Amazon also sells downloads.
Moreover, the desktop product (CD/download) is a more fully-featured product. It can handle all the forms and has Forms Mode for viewing/editing forms during preparation. The desktop product can also prepare multiple returns.
The Online Deluxe cannot prepare Schedule D,E,F, enter K-1, or a Sched. C with expenses. It does not have Forms Mode, and like you mentioned, a state return is an extra fee. Online Deluxe can only prepare 1 Federal return per account per year.
When purchased from Amazon, Deluxe comes in 2 versions--Fed & State combo, and a version that is Federal-only so be careful.
NOTE: You mentioned the state efile fee of 19.99. I just confirmed that is what Amazon is displaying. However, the current state efile fee is 24.99. (except free for New York). There is no fee if you print and mail the state returns.
I will notify a Moderator to see why TurboTax is showing a 19.99 state efile fee at Amazon. It will be during the day, however, before I have more into on that discrepancy.
