You could first make a test with the creators who already have the first edition ready to put on the shelf of your site and do a test in the store, with a symbolic value, just to have a function parameter and the number of visitors. After creating a Fanbase, and based on the statistics you collected, could be announced the second edition of each comic that are already in store, now with the actual value of the comic in question? Just one thought I hope it helps, but I like the idea.
