How about the new Lexmark toner cartridges for the Lexmark C930 or C935n?  (the “n” by the way stands for network).  $300+ per cartridge for an original toner cartridge.  You can find remanufactured versions for around $200 or slightly less, thats a handsome $100 off.  Or you can refill them for under $100, saving you about $200. Toner refills are not as common as buying new cartridges, but for 1/2 the price, they are very good money savers.  The toner refill kits from Atlantic Inkjet will work on almost all major laser toner printers, and usually save customers between 40 to 80% as compared to buying store bought replacement cartridges.
