What tricks do you know to extend the life of an ink-jet ink cartridge?

I rarely use my printer, and find that it probably costs me at least $1 per page as a consequence.

I’ve considered removing the cartridge, putting it in a freezer bag, the putting it in the freezer. Obviously, that would require thawing, but since I print so seldom, I’m okay with that?

Any input or other tips to save the ink?
