Yeah, ebay was a marvel when i was constructing my UW collection, and i still go there for odd import discs or meorabilia by other bands i like. But the ridiculousness of shipping costs and getting sniped by people that want to pay crazy prices for stuff that is, let's be honest, really not worth it, well, it's disheartening.
But i learned a long time ago collecting and pricing baseball cards that, in reality they're worth the 2 cents it makes to make em. Price and value is determined solely by what someone is willing to pay
