At the moment prices haven't been posted. There is supposedly a "screening procedure" they're doing with artist's alley and then we should know.
If they tell me a number I don't like I'll just have to pass on a table. Though I'm more inclined to think manga readers will like some of our stuff that people just into anime might not.
I have Bushidan, Wasted Life, and Shawn Goldheim: The Last Apprentice to sell there if I get in. Play to your crowd
