are used (epson) inkjet cartridges worth anything?

Question

We use to get a $3 credit toward our next purchase at Staples, but they have stopped giving credit. Thanks for your help

Answer 1

Empty cartridges *are* worth something. If not you
you, then to charities. There are many links. Two
random Stateside ones, given below ( which lead to
others).

They can be re-used and re-filled many times if not
in any way damaged; price depends on the make and
model of printer.

And finally, I certainly hope you responsibly recycle,
rather than land fill??!

Answer 2

Empty the cartridges are worth nothing, but you can refill them. That's much cheaper than buying new ones, but some printers accept only new ones.
