October Chaos Warrior Free Mini of the Month

Is this sculpt sold in any sets, or is it exclusive to the mini of the month program? My store ran out within hours of the day it was released so I didn’t get one but I love the mini and would be willing to buy it. It doesn’t seem to come in the box of chaos warriors they just released.

I’ve been checking eBay and surprised no one tossed one up there.

Also, if anyone wants to sell theirs for a reasonable price, DM me!
