"Random" Haha, you're kidding right? A new interesting way of selling crappy excess stock. A re-pack scheme where you don't even have to open anything. Clever.
I am going to post a drop myself that will include one random MTG booster box. $225 (MSRP $1,000,000)
Here are your possibilities (good luck):
Zendikar 1
Mirrodin 1
Innistrad 1
Modern Masters 1
Dragon's Maze 100
Homelands 25
Fallen Empires 32
