Amazon won’t let me sell a used book without a purchase invoice showing a bulk order from a manufacturer? This makes no sense to me; if anyone can clarify I would greatly appreciate it

So its been over 15 years since I last sold any textbooks on Amazon.

Back then, it was very easy, just enter the ISBN, describe the condition, and boom, that’s it.

So lately I decided to try selling some old college textbooks including a copy of “Algorithms for Dummies.”

Amazon makes you click on a “apply to sell” button and then immediately demands some kind of purchase invoice showing that I have purchased at least 50 copies of this book from a distributor in the last six months.

This makes absolutely zero sense to me. I am not a bookseller, I do not purchase large numbers of copies of the same book from distributors or manufacturers.

This is literally just a single used book that I legally purchased for a couple of dollars.

What is Amazon’s problem? They used to be more than happy to let you list your used books.

Is this no longer the case? Do you have to be a literal manufacturer to list books now or what?

If anyone with experience selling on Amazon can clarify I would greatly appreciate it. I tried emailing their support people but got no information or explanation whatsoever.
