Are these very expensive?

I am trying to upgrade the quality of the artwork in my house a bit, so I want to buy some original art prints. I can’t afford to buy original art, but I am thinking that prints would be a little less expensive, so I hope I can get a few at a time to replace some of the junk that is currently on my walls. Are art prints very expensive? I am thinking of the limited edition prints where they only make a certain number of them, not the ones that they make as many as they can sell.
