Status Updates From AS THE LIGHT DIES

I'm getting too irritated reading this book. I'm not going to finish.

Where does the MC get his money? He's a medically discharged Army Ranger from a poor family. He doesn't appear to have a job and yet he just dropped an estimated two or three hundred thousand dollars on 20 some shotguns and several pallets of ammo!!! He already had dozens of rifles and pistols so where did he get the money? Maybe he won the lottery.
