Actually, if you manage to sell a book here these days, at any price, you're doing pretty well unless it's some rare collectible.
The big sellers must have special postage contracts, because they can sell at prices less than my postage cost even if I sell my unwanted books without any 'profit'. That's 'profit' as in a few pence more than throwing it in the bin. The world is awash with used books. At least they're biodegradable, unlike plastic.
And recently I found my nearest charity book bin skip is no more. Why did they withdraw it? I happened to meet a council worker there who told me the story. It was regularly stuffed with other stuff, which they tolerated. But when the charity had to clean out a load of dog mess they finally called it a day.
