Music Magpie UK

They buy in nearly anything you can think of selling off. If you do not want to use eBay, Gumtree or Amazon use their services. Sure they do not offer much in terms of DVDs or CDs — their average buy in price is around 27p for an mainstream CD /​DVD — but for a truly rare one you can get up to £40 (that was the highest I had so it could be even more)
It works simple — you go to their website. You type in the title or bar-​code and they supply you with their buy in price. If you don’t agree with the price you simply don’t sell it to them.
Remember that their offer is free postage/​pickup and no advertising /​facilitating cost involved to sell it. So this time I sold 65 cd/​dvds and they offered £71 in total. I agreed. I packaged it in a cardboard box. I printed out a packing slip and arranged a pick up for 2 days later which was done as agreed. About 3 days after the pick up I got told all was processed and my £71 was being transferred to my bank account.
It is smooth, efficient and considering no overheads a good way to recycle your unwanted stuff and get paid for doing so.
They do electronics, clothes and PC stuff as well but I haven’t used that, but I guess the process is the same.
