If you print a lot of colour, this is a brilliant deal. You get a five month free trial of HP instant ink and then another £67 code which is enough to buy another 19 months of the £3.49 per month 100 prints contract. You can roll over up to 100 prints per month. If you print out lots of photos, this contract could save you a lot of money. The duplex printer/scanner/copier/fax or the 2 year ink deal is essentially free, whichever way to choose to look at it.
PC World is selling the 4658 with the five month trial but without the £67 printing credit for £79.99 which puts this deal into perspective.
Use the code FREEINK for an extra month of free printing. Thanks to the posters below for the code.
