I'd preordered the Official Companion, but hadn't thought it was out yet.
Open it up, it's a DVD set of the series. Maybe Amazon *meant* to send me the OC but screwed up the order?
Look at packing slip.
There's a note attached, from our friends in Northern California who had my 'loaner' set (Yes, I have an extra loaner set. Wanna make summat of it?).
The note reads as follows:
"Your extra set of Firefly DVDs were so shiny that we just couldn't give it back to you. Thanks for lending it to us, and please enjoy a new extra set!"
