Self-publishers do not “earn royalties.”
Stop thinking in terms of royalties.
Sales – COGS = gross profit.
Gross profit – overhead = net profit (aka ka-ching)
There are no royalties.
Royalties do not exist.
Say it with me now: Self-publishers do not earn royalties; they have profit. Now put all that “royalties” BS out of your head.
And Amazon? I know you know this, but you use the term deliberately to blur the lines between your retail business and your POD service. You know very good and well you don’t pay royalties. You give us a rebate on our rental fee for your stalls, you know, like at a flea market.
