Meritline offers two Canon-Compatible PGI-225 / CLI-226 Inkjet Cartridge 5-Packs for $19.95. (Choose the "2 Sets (10 Cartridges)" option.) Coupon code "MLC813XN" cuts it to $8.95. With free shipping, that's the lowest total price we could find for these cartridges, when purchased separately elsewhere, by $61. (However, we saw a single pack for 25 cents last week.) Each 5-pack contains a high-capacity black ink cartridge, regular capacity black ink cartridge, and a regular capacity ink cartridge each of cyan, magenta, and yellow. These cartridges fit several types of Canon PIXMA printers; see the "Compatible Printers" list on the product page for details.
