The black cartridges I've always been able to buy locally were the high yield or XL versions (in an economical 3 pack, 2 black, one color), however the color were always the standard yield, needing to be replaced way too often compared to the black. This one is high yield at good price so I'm encouraged that it will last much longer. P.S. I experimented at a big warehouse store with their cartridge refill service. The price was right, and though the cartridge worked, my Canon printer did not recognize that the cartridge had been refilled and continued to show the "low ink" warning light. Just saying.
