I haven't done FSA/HSA for a while since I never seemed to fully use them. However, I think it would be a good idea, assuming the plans can pay for that stuff.
I'm in the process of updating my various kits based on expiration dates, exposure (kits that I leave in the car), etc. Some of the stuff gets pricey.
Alternatively, maybe can start a "I have extra" thread like they are doing with the TP & handsanitizer groups on FB. I have a lot of bandage supplies from when I was taking care of family members that have since passed away. Stuff like tons of rolled gauze, tape, etc where I have a lot more than I could ever use. I have given a bunch away, but still have a lot more.
