Over years I had for backlist books something you may call a TBBI list - to be bought instantly. My ambition is to read at least all winners of some crime fiction awards (mainly Edgar, Dagger and Hammett) and some of the shortlisted novels too. At that I'm now over 30 years, and still a few books are hard to get.
With the internet and then digital books this list has "lost" a good deal of entries and its urgency too. Some may say, that some fun of "finding must read books" was lost though.
So now I have a TBB list for backlist books - and prize is one consideration. A prize of 8$ (or 8 Euros in our money) is acceptable for me. I see a change in ebook "re-prints" from cheap and quick & dirty (let' say in the 3-4$ bracket) to higher prizes with better quality conversions. I'm readily prepared to pay prizes for backlist books similar to "current" books if I can get ebooks with the page-count considerable higher than the error-count.
That said some prizes seem to be over the top. Example: Mary Willis Walker - Under the Beetle's Cellar - a novel from 1995, iirc out-of-print at least 15 years, and now available as ebook for 22$ (amazon.com).
This one stays on the TBB list, I'll wait for a prize reduction - as I say this my mouse hovers over the buy button ...
