Sounds about right; trying to capitalize on short-term demand. I've seen a Monster Dairy Delivery in the wild, but passed on it, as well as two Year of the Dragon Rodzillas (one came home with me, but I rejected the other because it was on a bad card, and I want the cars for my nephew to be on nice cards). Have yet to see the Mystery Machine, Bat, or Birds. With a little (or maybe a lot of) patience, we should all find them eventually.I have been to 7 Walmarts,1 TRU,and numerous other stores and yet to see any birds,bats,dragons,MM's or Monster dd's. What I do see is the remnants of the cases these come in. So my guess is they are being horded by ebay flunkies or flea market scalpers to rip off whoever is dumb enough to pay the stupid price.
