I did a survey of several places on the internet, Staples, Office Depot, and many others. I found 2 that were really cheap. (I did this for work and saved a bundle!)
I mostly use this one: www.4inkjets.com they have a good supply of low cost toner/ink. I think the other one I use is: www.inkjetsuperstore.com, but I'd have to look at work.
Sometimes the shipping is FREE!! :thumbup:
