Finally, a PIXMA PRO-100 ink deal! Staples has a triple-stacking coupon deal where you can buy two Eight-Color Packs of Canon CLI-42 Ink for net $114, or $57 each after a 40% Staples reward.

First, add two 8-packs of ink to your cart. Then, add any small filler item (you need at least $250 in your cart for some of these coupon codes).

Then apply the following three discount codes: 16869 gives you 40% rewards (towards a future purchase) when you purchase two ink packs. Add both 46066 and 56062 to get $60 off $250. You should see a price in-cart of $190 (plus tax). When considering the value of your 40% reward the net price is $114 for two packs or $57 per pack (+ tax).

If you don’t want to fuss with the reward you can still get a decent deal: buy one 8-pack of ink, add any small filler item, and use coupon 46066 to get $30 off $125. The ink would be $95 (+ tax) after coupon, which is still a great deal, and doesn’t rely on rewards.
