This ridiculously hot deal is back from the Canon Direct Store. When you buy the 8 CLI-42 (for PIXMA PRO-100) ink tanks individually, you get 24 “free gifts” of photo paper, totalling 440 sheets of 13×19″ (in semi-gloss, pro-lustre, and pro platinum), and 600 sheet of 8.5×11″ (in pro-lustre and matte).
The individual ink tanks cost $16.99 each for a total of $135.92, not much more expensive than buying the combo kit for $124.99. The (inflated) retail value of all the free paper is $1159.76, which makes your sales receipt look really silly.
This is a similar deal to the previous free paper deal which sold out very quickly. This deal ends on March 19th.
They also have a similar deal on PIXMA PRO-10 ink.
You can also use coupon code EIDPRM to get an additional 70 sheets of paper and free 2-day shipping. You will need to group your order in groups of 4 cartridges to be eligible to use the coupon code. (Thanks, Dustin!)
