They are expensive because you have to have them. The expiration dates are an FDA requirement. Good luck on finding a cheap source to buy them from. To get our monies worth out of them we use the expired ones as chest seals. Cut the cords off and put them in a zip lock bag and you are good to go. You just have to "burp" the wound once in while. I have used them on several shootings and a stabbing with good results.
