I make a point of shopping at our local bookstores, even though they are not always the convenient option, just to help keep them around.
I do wish bookstores focused more on their discovery and curation. For example, I’d probably buy a lot more books if they had a “if you liked this <popular book>, you might also like <less popular book1>, ...”
I even suggested this to our local bookstore but got a confused, blank stare :-(
