One of the main reasons (apart from the excellent print quality) I ditched
Epson and bought a Canon was the recyclable nature of the spent tanks. I
have amassed quite a few now and cannot find anywhere offering such a scheme
(and I know I've seen a few in the past - but can't find the sites now I'm
looking!) Typically the recompense was between 10 and 15 pence per
cartridge, not much, but the charity I have in mind (a local fund set up by
the parents of a little boy who died of an extremely rare form of leukaemia)
would be grateful for every penny.

Does anyone know of any companies offering such a scheme?

Thanks
