Yeah, like I said earlier, there seems to be a corps of eternally hopefuls on Amazon and a couple other sites trying to find the one sucker willing to pay too bloody much by a long shot for used books.
If the books were actually worth that, I would have cashed in all of mine long ago. Dunno what the business mode is, whether it's crack pipe based, or someone that simply doesn't actually want to sell but will, if someone is stupid enough to buy, but in either case, it pretty much amounts to being so off base that they seem not worth even contacting, as the price and reality are so far apart.
I particularly wonder, when I see new copies and lots available for say, $20, and a couple used copies starting at ten or more times that. Dunno.
I tend to haunt the used book stores, and especially the piles of books at gun shows for decent gun related books. Worked for me so far. Likely will too, until someone decides that theirs are worth what they saw on Amazon!
