I'm curious if anyone has experimented with educating potential customers about the fees associated with each delivery option. For example: 1. Buy on Amazon.com for $9.99 (I earn $5.10) 2. Buy on iBooks for $9.99 (I earn $7.00) 3. Buy a PDF for $9.99 (I earn $9.25) If I felt any connection or goodwill toward the author (highly likely) I would be inclined to pick the best option for me _and_ the author.
