I can see the limits on AppSumo, but frankly I'm tired of getting an LTD in beta stage, hoping that it will improve over time and supporting the development with feedback... only to be left in the dust as new features are introduced for premium plans. I understand that you've got to run a business, but if you can't afford lifetime deals, don't offer them. And if you can, limit them to get just enough early adopters on board.

As this deal stands I'm not biting. Plenty of other alternatives out there. I'd expect the basic plan at tier 1 and 2, with the plus plan sold at tier 3 and 4.
