Hi Selma,
If you don't get any takers on this site, I am sure you can find a good home for your supplies elsewhere. Ostomy support groups often have a share table, and rest homes and county social services for uninsured might be interested. There's a great group called Girls with Guts that would be a very worthwhile place to donate, but I don't know their procedure for accepting supplies. Even if you don't donate supplies to GWG, I encourage you to check them out on FB or online.
Thanks for the offer!
