... "darned if I can’t find any Amazon purchases that qualify."
So of course I went over to investigate. I have 39 purchases that qualify, as of my current check.
A few years ago, I bought copies of Aldous Huxley's _The Perennial Philosophy_ as gifts for other people; it had been a huge influence on me during what would now be called my "quarter life crisis". Because I bought p-copies through Amazon, I can now buy a kindle copy for $2.99. I may.
I could also pick up a kindle version of Mini Mickey from 2011; I definitely won't buy that, even for $1.99.
Most of the rest of the list is genre fiction. There are numerous Terry Pratchett novels; if I ever decide to reread them again (unlikely), I can pick them up for a couple of dollars each on kindle. Jennifer Crusie and Bob Mayer collaborated on _Agnes and the Hitman_, which I am unlikely to reread. I found Loretta Chase's _Not Quite a Lady_ not quite readable, so that's out. Ah, but the highly erotic MMF Regency _Phyllida and the Brotherhood of Philander_ is available for $2.99! Probably the most tempting on the list.
Several Kim Harrisons, more Loretta Chase, some parenting books (_Scientist in the Crib_, 4th ed. of _Nursing Your Baby_ -- I weaned my last kid a couple years ago, so not a lot of point there). _Horse People: Scenes from the Riding Life_ by Michael Korda was a book I bought for a friend in Xmas of 2004. I'll ask her if it's worth reading; at $2.99, maybe. Some romances: Rachel Gibson, who I don't read any more, but SEP's _Nobody's Baby But Mine_ is one of those horrifying premises that works disturbingly well. I've reread it a lot. I might reread it again for $1.99. If I get really, really sick. I also don't read Elizabeth Peters any more, altho I could rebuild that collection on the cheap if I wanted to.
When I was still working for a certain online bookseller, I bought a bunch of books on negotiation, because I wasn't happy about how that was working for me (I figured out the problem: some people are not negotiating in good faith, and the Best Way to deal with that is to Not Be Around Them. Which is one of a long, long, long list of reasons I don't work for that company any more. Second most overdetermined choice of my life.), including _Swim with the Sharks Without Being Eaten Alive_, by Harvey Mackay. I got rid of it in favor of not swimming with sharks. Should I decide to swim with sharks again, perhaps I would reread it for $2.99.
Georgette Heyer's _Cotillion_ and _Sylvester_ are each available for $2.99. Those are moderately tempting.
Oh, and _Good Omens_. Which is a truly excellent book, but I can only reread a book so many times.
When kindle matchbook figures out what is available for you, it works backwards through what you have ordered from them. My most recent available purchase was bought in 2011 (the Mini Mickey). Virtually everything else was bought from before 2007, and about half of the available items I bought in paper over 10 years ago. In fact, #21-#29 are from 1999 or earlier. The earliest purchase was from right around when I started that job I mention from time to time. My earliest purchase _ever_ from Amazon was placed December 22, 1995, for Herbert O. Yardley's _Education of a Poker Player_. It was a gift for my then boyfriend, who would interview at that online bookseller shortly before me, and we started at around the same time (along with another co-worker of mine from Spry). None of us appear in a certain book that came out recently about that bookseller. In any event, Yardley's book is not (yet?) available through matchbook. I might buy that, because, hey, history!
The books available through matchbook are the kinds of books that Just Aren't Selling Like Hotcakes Any More, especially in paper, but they are also the kinds of books that if you are still collecting, reading and rereading in genre fiction, you might well fork out for a copy for completist purposes. This seems like a classic Jeff-program: camel nose in by showing people they can make money off of stuff that they don't think they can make money on, and then coerce them into offering up everything else for sale, too.
Awesome for readers, and basically, that's what I've always been.
