Currently, I am unable to offer a discount. I have all the volumes, and the discs are generally in good condition. I have confirmed the numbering on the discs and jackets. The jackets have some age-related staining, and the box also has considerable staining. There is no odor or discoloration, so it might not be very noticeable if you wipe it off. (However, if you are concerned about the stains, it might be best to refrain from purchasing.)
