Replying to Broken Ski Idea

Alright here's an idea i've been sitting on for a while,

Most pairs of skis that you buy, as soon as one of them breaks, the skis are completely worthless to you, and the other ski that you still have that has plenty of life left in it goes to waste. It is reasonable to assume that someone else out there with the same skis has one broken ski and one good ski, so what if there was an app/website where you could browse and find a matching ski for your good one and either sell your single ski to that person or buy their good ski from them?

Let me know what you think
