First-edition Blu-ray purchased on Amazon. Includes a serial code for the all-volumes purchase bonus: a roundtable CD (cast members not yet determined). Of course, it's unused. It's sold out on Amazon, so how about it for those who want to get the bonus? The disc has been opened, and the bonus disc has been played once. I think it's in a clean condition without any stains, but please understand that it is a used item.
