Yerdle is a swap site with a mission. Its founders are convinced we all buy and own way too much stuff. They want their online swapping platform to help reduce the number of new purchases by 25%. When you post an item on the website, you earn Yerdle Dollars, which you can use to ‘buy’ something else. The platform is not about making money, but about taking an anti-materialistic stance and putting a stop to overproduction.
