Here's the great LifeHacker thread post where I originally found the information:
Entrepreneurship: MyCorporation Founds Your Company for Free This Week Only
no aff link, of which I'm aware. There's a decent review there of the service.
Here's the direct link:
Free Incorporation, Free LLC Formation Services :: MyCorporation
I used an agent in Delaware to incorporate for about 200 bucks and continue to use them to maintain my business in good standing there, since I'm not located in Delaware. This deal looks even better.
Only one day left though.
