The kids have a homework assignment due tomorrow, your husband wants to print off his resume for a job interview, and little Bobby wants you to print off some more pictures for him to color. This is not a good time for the "you are running low on Canon CLI-226 ink" message to flash up on your monitor. Your Canon PIXMA printer is in constant use, so it is important to have a good supply of ink cartridges on hand for this sort of emergency. The problem is that ink is expensive, and you need more than a single Canon 226 black cartridge. You also need CLI-226M, CLI-226C, and CLI-226Y cartridges for color printing. Fortunately, reliable sellers on eBay have a wide selection of ink cartridges for all makes and models of printer, and they often offer bulk discounts. You can stock up on your Canon CLI-226 ink in advance and avoid all the drama the next time everybody wants to use the printer at once.
