Used books are hard to move. This is one reason why most libraries don’t take donations. These sales are for clearing shelves more than for making profit.
Not hard to move. Almost impossible to move.
In my shelf I apart from some old leather bound books from my grandfather (Churchils world history, complete Hamsund) and CE and hard cover 40k books I have nothing but paper trash
I use the Norwegian finn.no (listings of everything from old books to cars to houses. Norway is such a small market that one service covers all)
It’s perfect for selling used (but little used) baby and child stuff. I have also bought a lot off Lego Duplo.
