I pay for a stand-alone and the only upsell I can recall seeing over and over again is "audit protection" for ~$59 or so. Is the free version filled with add-ons?
And the state efile (but since there's the "free" alternative to print out forms and mail in that's not a big deal, and it's relatively cheap anyway). I've also always used the desktop/standalone version, great time saving compared to doing it on my own.
It's intentionally obtuse and confusing for something that should be simple and straightforward for 80% of the population.
