Hi Michael,
The error most likely occurred during the packaging of the boxed set.
If you could send us a proof of purchase (either a copy of the receipt or a photo of the set next to this email), we'd be happy to send you the missing Sympathy for Mr. Vengeance disc. Please include your address information in your email as well.
Thanks for supporting the Palisades Tartan brand.

We're working to fix the problem as quickly as possible.
