I've had cartridges here for over two years and when I do open the ones I need they're fine. And mine have all been refilled at work by my friend. Been ages since I bought new ones, the cost is $27. for one black at Staples , don't remember what I used to pay for the colored cartridges. If I can keep getting the cartridges refilled I'll be happy, what a saving, and so much handier than having to run into Staples . We have other stores that sell them but I found they didn't last. My refills on the other hand seem to last forever-- and I print a lot of pictures and other stuff .
I keep them in a plain small zip lock bag in one of the drawers in my computer desk.
