Omg another loved of literature who doesn't hoard books and isn't precious about selling them! You get it! Tbh twenty years ago I would have been horrified by the idea. But you often only read things once and then they gather dust. And a weeks worth of groceries can't be sniffed at.
It appalls me how little books are valued though. I have some mint books 📚 that cost say $30 at the store brand new but I can't sell them for $10. Wtf??
