Canon Repeat & Save is Canon's scheme for helping you save money on printer consumables. By signing up for repeat orders, you can save up to 5% on selected products including toner and ink. It's a modest discount but one advantage is that you can simply decide how often you'd like to receive a delivery and Canon does the rest, so you don't have to remember to order ink regularly. It's possible to cancel at any time if you find your printing needs have changed.
