I sold a Lemon Jelly LP on Discogs for 100Eur recently, bought on a whim when I once worked in Tower.
A lot of vinyl releases keep their price quite well as they're limited.
I've been selling off a good chunk of stuff the past year or so, but only stuff I don't have much time for anymore, there's a core collection of things I'd never sell unless really desperate.
He's got some nice things on there, might get some sneaky bids in.
Looks like he's raided his little sister's cd collection too for some extra funds. Good man!
