Canon CLI-8 4-Color Multipack Ink Tanks Customer / User Review

I've discovered that the inconvenience may outweigh the few dollars saved by purchasing the combination pack. My Cyan and Magenta cartridges lasted only 4 weeks and 6 weeks respectively while the others are still going. Purchasing more combination packs would have resulted in a backlog of unused ink.

You might order the package now and then (I wish it included regular black ink), but given the staggered depletion of ink cartridges, it frequently makes more sense to order the single cartridge. Moreover, the combination of Amazon's one-click ordering and no-postage Prime membershp makes it no less practical for the consumer to order individual cartridges as they expire (though I'm sure Amazon prefers to send out large quantities in the same order).
