If your VHS tapes include anything taped from the telly...old shows no longer on anymore then maybe you should YouTube them for the sake of popular culture.
If you have any records by Virginia Astley/Stereolab/Vashti Bunyan then I'll er, take them off your hands!!
Charity shops are the obvious place for old vinyl - especially Oxfam - as they have volunteers with the knowledge to pick and select ones which will sell.
Or you could go all 1978 and turn your vinyl into ashtrays!
