By the time you've slapped on an extortionate £1.50 or £2 p&p charge you should get a few quid per video.
I gave mine away to friends & family who don't yet have a DVD player There were a hell of a lot but I couldn't be bothered selling them especially since tape is so easily damaged and when you sell people complain if things are not perfect (and rightfully so too). So was more hassle than it was worth to me and friends & family were grateful. Might get a few freebies off them in future as a result
...or you could always try giving them to the local charity shop. I am sure the good people at Scope, Age Concern, Barnardos etc would welcome a few quality videos - or even stick them in the collecting sacks that get shoved through your door.
You never know when you or somebody you know will have need of their services at some time.
I'm off now to cure some sick children and feed a few thousand people with tuna sandwiches.
another idea....... we have a place in town called cash converters. Apparently you can get money from them for this sort of stuff. The alternative is you sel the whole lot as a package for a small sum and hope to get lucky. It took me about 4 months to sell my lot, but eventually there will be someone with an interest.
Our local market has secondhand cd and DVD stalls, they are generally interested in collectors editions and unusual stuff (steady), like IOM TT races and concert footage, but will give you a small amount (usually about a quid ) for other titles or exchange them for secondhand DVD titles,.
