Where in the world are you getting 500 page yield ink for $2. When you compare prices you should with oem prices, and not aftermarket crap. I can manufacture cheap laser cartridges too, but that would not be good for my rep. Dude I work in this industry and know what i'm talking about. I know most all of the huge aftermarket inkjet manufactures. There is a big problem in the ink industry with getting the aftermarket ink right. 95% of the inkjet remanufacture out there have 20 to 50 percent reject rate. The epson and canon ink tanks that don't have the printhead are a little easier, but for the most part aftermarket inkjets are not up to par with the oem, I'm sad to admit. I am within an organization that is currently organizing a standardize test method, similiar to what we have for all in one toner cartridges, but made strickly for ink. We are hoping this will help the situation and make companies follow standards to repeat quality.
