I have been told that nursing homes would be more than happy to have the pants / pads as donations. I made a few packs of samples for a local group to give to pending surgery patients when I though I was almost done with them.
A local family assistance program in my area accepts them to give to elderly folks (like us ) who are having a bad financial time of it. Just be sure the size is on the bag.
I had hoped by now that I wouldn't be using them anymore - but the prospects of reducing that expense are dim.
I asked the assistance folks about my extra surgical stuff - they said there is no end to the kinds of requests they get but can't fill (the real answer was "bring it on by").
The other day on a trip I was scrounging in the car for a pad, hoping I had a spare somewhere -
