Is there such a product where you can store ink cartridges when not in use?? I don't print a whole lot.?

Unfortunately no. You could simply store it in a (quality) baggy with a damp cloth. That will help to avoid drying of the printheads on the cartridges. I've done this for cartridges and had them last about a year. Normally in your printer the cartridges begin to dry out (printhead) and cause clogging after about 2 months.Is there such a product where you can store ink cartridges when not in use??

Get an airtight container. Put something in the bottom (like a couple of old ball point pens) to hold cart off the bottom, put some water in the container (under the cart) , seal the top of the container. Put somewhere it will not be disturbed, and leave.
