Summary: Found this item on sale for about a third of the original price, so I bought a few. The employee told me Canon must be discontinuing this item or something. While his explanation was nothing useful it was nice to find this on sale since print cartridges are expensive.
Summary: I have always used CANON INK & CANON printers. I just hope that they always have a printer for me. In my opininion, you can not beat a CANON PRINTER or CANON INK for the quality and the price. I have used LEXMARKS, HPs, etc. as other family members have these. These printers (and inks) do not come close to my CANON for QUALITY and COST of Ink Replacements.
Summary: My only problem with the black ink is that it runs out way too fast if you are using standard print settings on your printer. I own a Canon MP610 and to get a decent amount of copies printed with my black ink I constantly have to use the draft setting.
