Reminds me of one of my unsatisfactory experiences with Amazon. These days, I usually I order from Amazon.ca (Canadian Amazon), but back then I ordered from the American site.
I saw that they had a particular book that I wanted to read. Hardbound & new, not available as a ebook. Price was around $40. The page said they had it
in stock. I ordered (& paid, of course), and they emailed an acknowledgement. I was waiting and waiting for its delivery, and finally I contacted them online inquiring about the delay.
Their reply was it was actually out of stock, but I reminded them it was reported "in stock" when I ordered, and I'd ordered in good faith. Then they said "out of print". I still wanted the book and they proposed a refund. So I told them I'd noticed that online used & rare booksellers were offering it for $100-150, and i suggested that Amazon make good on my order & payment. Just obtain one of those and send it to me. Nope, they would not.
For a ginormous company with incredibly deep pockets, I considered it a bad-business move on their part. The customer loses.
