Books are seemingly more expensive than ever but paradoxically declining in material and substantial quality (i.e., are poorly edited and printed). Buying used books is just good financial sense.
I can also find decades' worth of quality books for prices that sometimes drop below $1 (though popular / rare books are frequently sold for more than their original asking price now, but inflation-adjusted, that is still a good deal, and much less than a new book). There is no reason to expect that just because something was just published recently that it is worth many multiples the cost of an older book. I will still buy new books to support authors I particularly like, but as prices keep going up, I find I am becoming more and more selective.
And finally, physical books do not spy on me or show me ads, or otherwise try to coerce me into an abusive relationship, like every other form of entertainment seems to attempt to do these days.
Our local independent book shop got together with a couple other dozen and started a used book platform. If I have a book I don't want, I'll let them know, if they have a buyer, I just bring it to them and get a small amount of money. They take a fee for the handling and everyone's happy. A used book is usually max half the price of new and there is a decently wide selection.
A lot of online retailers have also started stocking used books as a cheaper alternative.
I suspect I misunderstood you and by "new releases" you are referring to non-used books. Yes, the entire point is that they are too expensive to justify purchasing.
Could be the makings of a dark age.
