Plenty of these for $1 ea. Apparently the 2nd last digit on the embossed numbers near the barcode, denotes which fig is inside.
$12 for a complete set sounds like a bargain, too bad we are not minecraft fans :(, but I'm sure there are plenty of fans here on ozb. This was I believe in officer, vic. Enjoy!
For those wondering, they are really small. Really, really small. It's about half the height of a Bic lighter.
Also, these are blind bags (or boxes in this case), meaning there's a random figure in there. You'll need to buy way more than 12 boxes to have a complete set.
