Yeah, if there's a problem with the assigned number the right thing to do would be to remove it from sale until they can resolve it. I don't know if you follow the classical box thread, but popmarket recently listed a huge Itzhak Perlman box on discogs for a tiny sum; in that case, two or three people got the correct box and the rest got a different CD entirely (and never the same CD, which tends to suggest the problem goes beyond an ISBN being linked to the wrong product). For the Blancmange set, $22 seemed a plausible price, so I thought I'd chance it. I'd say I'll boycott popmarket in future, but they're also deepdiscount, aren't they? And that won't be happening. I probably just won't buy from them on discogs again.
