Today is Final Order Cutoff (or FOC) for The BUNKER Volume 3. This is deadline for retailers to finalize their orders. What you need to do is pre-order with your local comics shop using the Diamond Order Code: AUG151640 if you want to ensure a copy for yourself. If you don't, you leave it to fate whether there will be any copies in stock. It's as simple as that.
The BUNKER Volume 3 will be in stores December 16th, 2015. Your future will never be the same.
