1 Save With Refilled No. 57 Ink Cartridge
The professionally refilled cartridges work well and save money. Also, you can save additional dollars by returning your used cartridges to the ink refiller. If you do not wish to refill your cartridge, the refiller will pay you for your empty. Another option for your empty is to take it to Office Max where they will give you a free ream of paper for your empty.

2 Beware of Inkgrabber.com
Inkgrabber.com is listing refurbished and they send you compatible. BEWARE they do not sell what they advertise. They had no feedback when I made my purchase, so here is some accurate feedback.
3 It's cheaper here than on HP.com!
HP.com is selling this exact same cartridge for $34.99 so I say, get it here for the better deal :)
