Author from original post here! For clarification, this is not a new thing, but something I learned to do from this post:
https://bsky.app/profile/kristadb1.bsky.social/post/3kb4wbix...In her case, she ordered author copies (that gives you no royalties, of course) and got the same copies sold again to herself as author copies.
In my case, I also ordered author copies, but they were resold to a normal customer after I returned them.
From an order of 50 author copies, I returned 14. Packaging was fine, so it wasn’t a problem with how they bumped up during shipping. They were misprinted, or had folded covers (they tear easily after a fold, really bad), some were printed beyond the bleed area (that’s what bleed is for, you can’t be printing beyond it), and a few were printed slightly off angle. One particularly bad copy was even cut an inch smaller than it should’ve been, trimming every single page and cover, text and all.
So yeah, that’s why I returned them. But I do give you that some of those defects would go completely unseen by someone at a warehouse. You flip through the book, all pages seem to be there, but how is a person there supposed to know what the margins of the book look like? But most errors would not pass a regular printing press QC, particularly the damaged covers.
Also, Amazon both prints and distributes these books, so QC is in their hands from the start.
