This week, mine stopped selling on Amazon.
I recall the last recession when, on another site, we theorized that in bad times people would turn to books for encouragement or just to escape the depressing news. I'm not sure it works that way any longer. For one thing, there is the additional problem of publishers not having the money to buy more books or to promote them. Then the stores aren't likely to take chances but stock only sure-fire sellers, and not too many of those.
I think perhaps that we've reached a point where people who are saving save first by not buying books. Books are the ultimate luxury when one can get them at the library.
If anyone here has some cheerier statistics or facts, by all means share. I'm getting seriously depressed.
