This is a pretty good deal I think, cheapest elsewhere is ~£30 delivery. You buy the printer and then fill in this form from cannon to get £15 cashback:http://www.canon.co.uk/Images/UK_MP210_v3_online_claim_form-v1_0_tcm14-541633.pdf
Quidco should be on the full amount and works out to be about £4.50 so printer around £20 delivered!
Unfortunately it seems vouchers don't work with this item, but it kind of figures.
Hope its useful for someone....
