God, that's quick! You may have noticed a sentence at Amazon - something along the lines of "David, make £193.79. Sell your past purchases at Amazon.co.uk today."
"What have I got to lose," I thought to myself, and put on offer four CDs that I never listen to. Two hours later, I've already sold three of them, making £25. Much quicker and easier than Ebay. Perhaps I should put my entire collection up for sale - I could make a fortune.
Amazon offers a credit towards postage. You can sell CDs, DVDs, videos, books, toys, software and computer games, but you don't have to have bought the item through Amazon in order to sell it.
