These digital camera resources give you links and tips for where to donate, sell, recycle, and toss your old digital cameras.
Donate
Youth in Focus
This organization helps teens interested in photography explore and grow their skills by providing them with the means to learn.
They “accept most digital cameras in good, working condition, made within the last 5-7 years” and almost all 35mm/120mm cameras are in working order. Any lenses and lighting are also welcome.

Buy Nothing Groups
You can also get rid of your cameras locally by posting in a Buy Nothing group on Facebook or Nextdoor. Buy Nothing groups are just for donating old items. You leave the item(s) in your mailbox or at the end of your driveway, post it in the group, and someone in your community will have the chance to come and pick up the item at your location. No mailing, shipping, or driving is needed!
Sell
Resell your old cameras that are still in working condition online. Here are a couple of online retailers you can use for reselling:
