I have a whole load of old ink cartridges that I don't want to throw away. Anything I can do with them?
Was thinking of something on the lines of trading them in for vouchers.
Staples have an offer where they give £1 per cartridge but the only draw back is that I can only spend it on the purchase of another cartridge, and the T&C states only one voucher per cartridge purchase :x so in effect its £1 off per cartridge.
Surely there has to be something better out there!
