I was slightly surprised earlier today to visit an online music store (ie a dedicated used music site as opposed to ebay etc), and read one dealer saying he did not cite case condition as jewel cases are swappable, and could if requested post without - as if the case is generally taken not to be a crucial part of a used item. I've always assumed if I'm buying 2nd hand that dealers sell on goods as is, otherwise everyone would be exchanging scratched cases for better ones in order to reclassify condition wouldn't they..?
Do you care as a rule if a cd is sold exactly as it was originally - or only if it's really really collectable?
