We had a fabulous local book shop that bought second hand books but that sadly closed in lockdown.
I therefore wondered where the best place to sell books is? They are in a good condition and many are very expensive to buy new.
I tried "we buy books" and eBay a few years ago and didn't have much success (I also was appalled at the extremely low prices WBB are offering for books too!)
Is a car boot/garage sale the way forward?
