It saves me to have to go to the store ! and look and look till you find what you are needing. I do however, would like to see where what you are needing would come automatically before you run out.
Have been buying the 932/933 cartirdges a long time; easy to order, delivery quick and FREE. Print quality is fine and does not gum up printer heads. Pricey...! The XL versions do seem to last much longer and appears cheaper per sheet, especially if print mainly in DRAFT..
I always buy the XL High Yield Ink Cartridges because the price is good and because the cartridge is a larger size, it lasts longer. I like not having to worry about running out of ink when I need it most.
