I know this is a problem, but it's so egregious, I have to ask for myself. I have boxes of used books, many are my old books I got new, many from thrift stores, etc. I sold books years ago on Amazon and didn't have this problem---if I recall correctly, it was just like...category ungating then? But now, I'm being asked to provide supplier invoices for like.... HALF of the books I want to sell! What!?

My AHR is 200. I have 0 issues. I just started selling books again so I have under 10 orders so far. I am at a loss for reasons why this is so bad for me. What adds insult to injury is that there's a bunch of other people selling that used book. No way that they all bought them from a "distributor" or "manufacturer". What is going on??? Is selling books on Amazon for normal people just like...dead now?

For example, I got John Lewis' March trilogy. (First book: EAN: 9781603093002, ISBN: 1603093001). There are 200+ used for sale, super cheap. All these people got directly from the manufacturer or a distributor in bulk? No way.

Update: the Amazon customer service representative basically told me that if I want to sell HALF OF MY USED BOOKS (which first-sale doctrine SHOULD apply to but clearly doesn't on Amazon), I have to have formal Letters of Authorization from the publishers!? This is the opposite of first-sale doctrine! Giving publishers the power over whether or not I can resell MY book! If I go to Barnes and Noble, buy a Harry Potter book, Amazon will NOT let me sell it unless I have a formal business and a relationship with the publisher??? There are 720 copies for sale of this harry potter book (0439784549), but I doubt all 720 people have gotten explicit approval from the publisher. I tried googling it and I can't even find information about getting LOA's from publishers.

THIS IS COMPLETELY INSANE. Okay, small-time book selling on amazon for everyday people is officially dead.
