Does anyone buying an "exclusive" copy actually believe they're getting that? The pricing is also interesting from another angle, if we take them at their word ("5 copies" vs "exclusive"): why accept 25% less overall? Assuming this is a cryptocurrency transaction, it surprises me the simplicity of dealing with a single buyer is worth that. Can anyone with more insight explain?
