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.
