Here's what I'm doing for pricing on ASE2-3. It's 147 pages, 50% longer than ASE1 (both word count and pages), took twice as long to write, and art cost are more than twice those in ASE1. So I intend to net $15 per sale rather than the $10 I net for ASE1.
That puts prices at:
ASE2-3 Publisher Grade Paper (int'l shipping is expensive) - $25.09
ASE2-3 Standard Paper (cheaper for international shipping) - $26.56
ASE2-3 PDF - $17.66
I think that's fair for nearly 150 pages.
I'm also debating the need for a publisher grade option at all, but hey, $1.45 savings, so I suppose it's useful.
