Insulin needed.

Since the cost of insulin has gone up so much and my boyfriend does not have insurance currently he is unable to buy more, he's almost out and I honestly don't know what to do. It cost more then both of our checks combined and we both have other bills to pay as well. He's almost out. They only sell it by the box apparently which isn't helping and is partly why we can't afford it. Please anything help would mean the world to me, I don't know what will happen when he runs out.
