Used printer ink cartridges

[Binky]

I have a number of used printer ink cartridges. Does anyone know of a organisation that might pay me for me or give me points on a points card? W H Smith did this one year, but haven't repeated the offer. Thanks.

my local tesco has plastic bag envelopes next to the cartridges section so you can send them off for recycling and reward points.

or, my local school collects them and gets some money for them.
I don't think it's really worth doing unless you do it in bulk.

they're worth good money on ebay, just search for empty cartridges and you'll see
