content: My local Walgreens store refills Dell ink cartridges; the printer does not recognize the refill and will not accept them. You can override the printer and force it to print, but it's a hassle if you do a lot of printing. Best to stick with the real deal. Best Buy has Dell ink available online for a better price than Dell online. Staples has Dell ink for about the same as Dell online, but at least you save shipping and handling if there is a store near you. Office Depot has discontinued the Dell line and gone to an allegedly compatible store brand. Cost seems to be a bit higher than Staples though. So overall, if you need it now go to your nearest Staples office store.
