According to 'the defendant' that value is all of the money he got from Bob Wolff over a couple of Years not only from the discs. The discs returned a lot less. Though of course that might be a lie, I wouldn't know.
The purchase order says $28k for 8k disks. It would be funny if he's telling the truth, and the fake PO that he made for an unrelated reason came back to bite him here...
