I was offered £2.28 for what i considered a fairly rare DVD, decided to take a punt on Ebay and got £21.25 plus postage, bit of a no brainer really. I would do what a previous poster said sort through your collections, if you think any of them are a bit out of the ordinary take a chance on ebay, likelyhood you will make more than you would of these rip off merchants. Any run of the mill stuff is probably worth lumping together and selling as a job lot, don't expect much though.
