Just ordered two HP compatible laser cartridges (immediate use & a spare) for $53, which includes shipping.  One original HP cartridge is $68.99 at Staples.com.

Right now ComboInk has a promo code for 12% off all ink, toner and printer accessories.  ComboInk remanufactured cartridges cost a fraction of those at the big box stores and I’ve never, ever had even the tiniest problem with either my laser or ink cartridges.  Great timing because my laser is running lines and this is my back-up cartridge (bad Goddess!)

They offer a One-Year Money-Back Guarantee on all ink cartridge products, if you are not 100 percent satisfied with its performance.
