> Of note: if a customer orders a copy from Amazon, and a damaged, returned book is shipped to them instead, no new KDP printing orders kick in. This means I don’t get paid at all, because they only pay me when a book is printed.
Why wouldn't this be true? Why would a return that is then resold result in a double royalty payment? Is that something that happens for traditionally-published books that are returned and resold?
It might have to do with the fact that these particular books were "author's copies" but I don't have enough information about how those work in a print-on-demand context to know whether this actually results in a loss of royalties in this case. Did they pay for them to be printed as a self publisher or were they provided for free as part of a contract with an external publisher? Does Amazon's internal system distinguish between "author" copies" and other orders, or do you just order some copies of your own book via the standard interface? Would the author's replacement copies go through that same system or would they be printed like normal and incur royalties? No idea.
