While there are some books you’ll read again and treasure, others are simply taking up space on your shelves and could earn you some extra pocket money. MoneySavingExpert suggests you head straight to Amazon Marketplace if you want to earn money on unwanted books.

Search the title, add a quick description and sit back until it sells. It’s free to list up to 35 books a month, but Amazon will take a 75p (90cents) fee, plus 5.1% of total sales below £5 ($6) and 15.3% for total sales greater than or equal to £5 ($6). If you’re selling on some of those pricey textbooks, you could make a tidy profit. Otherwise, try We Buy Books, for an instant price and no postage to factor in.
