Castle Ink has a better selection of toner and printing cartridges than most of the big box stores and their prices are often better. If you need your supplies delivered they have prompt reliable delivery available.
I have an older HP all in one scanner/fax printer where finding cartridges is often not easy,but Castle Ink always seems to have them. I also have a an HP laser printer and their toner prices are better than the competition.
The customer service here is far superior to the big box stores too.
