Hi, !
First off, I am so very sorry for the loss of your husband. I do hope you have plenty of support as you weather this unexpected change.
Secondly, I think it's great that you are wanting to make sure things he purchased can get used by others in need. If you are comfortable with a space like Facebook Marketplace, you can try posting a listing there. It's not without its flaws, but I use Facebook Marketplace more than any other app or site. Also, you can sell items through Nextdoor, which is a site/app focused on your specific area, so it would be a good way to sell the device locally. Also, you can try Ebay. This is a site dedicated to selling new/used medical equipment -- https://bimedis.com/. I am not personally endorsing the site, but it may be a good place to check out. Also, selling can be a real pain and take a good chunk of your time, but it may be worth the effort to recoup some of the cost of the equipment. And here is another site that focuses on selling medical equipment -- https://www.dotmed.com/. As always, please be safe when selling online. I hope this information helps!
Best, Erin, Team Member.
