Im guessing this deal wont be suitable for that many people but ...
if anybody is still using a canon printer that takes cl38 / cl41 colour ink carts (like me) then you can currently get them pretty cheap at the moment from ebay via the link provided
For example 2 carts for £4.03 delivered and 4 carts for £6.11 delivered
They are listed as cl38 which are basically the same as cl41 apart from the amount of ink - these apparently have been filled with 12ml of ink (as opposed to cl41 which have 16ml) - even though its 12ml & not 16ml of ink .... at £1.53 a cart this looks pretty good value to me
Ive been using my canon MP210 printer for around a decade now & its still working perfectly so wont be upgrading till it eventually breaks down - the bonus is that compatible carts for this printer have gone really cheap now
