Today has been a terribly long day and my eyes are about to fall out. Work is kicking my butt but I am kicking back and winning!
Before I forget, I wanted to share a site for finding the best deals on printer cartridges. Ironically enough, it's called Cartridge Finder and it's such a simple site in concept and look and feel but it is quite handy. Not only does it display info about your cartridge but also pulls in pricing from PriceGrabber.com to show you the best prices. From there you can click on the merchant pricing of your choice and go to the merchant site to order your cartridge.
The really cool thing for us is that we don't do much printing so our really old HP printers are still working well for us. I was surprised they had information and merchants available for a printer over 8 years old.
