First, 'ditto' on the comments above.
Or you could take it as a compliment. The DVD and magazine are so highly thought of and coveted that the DVD, even without the excellent magazine, fetches such a nice price.
Hit 'em back! Sell the DVD too! Obviously there is a market for the thing, and you've got the sales thing figured out through the web site.
Which reminds me, I need to get my DVD and magazine back from the guy I loaned them to!
