The wife and I decided to get rid of some of "my" extra stuff, like unused professional equipment from my former career.
I got a few bucks from the stuff on Ebay and laid into survival supplies:
(I'm not going to mention specifics, but):
masks, gloves, tape, ponchos, safety glasses, weapon lube, body armor, ammo, etc.
ETA: bleach, spray bottles, hand sanitizers, disinfectants,
