There’s always a chance things can turn up for a fair price if you keep your eyes peeled but with Discogs being a source to check values, even charity shops are looking for gems they can make money off. Haven’t seen a decent cd in a charity shop in my town ever. Westlife, Daniel O’Donnell, Richard Clayderman, James Last and Jive Bunny etc etc are available in abundance but if you want a decent rock album, you have to have some serious luck to grab a bargain these days.
