To differentiate secondhand selling app letgo from its competition, we created The letgo Commercializer - the first and only way to create a million-dollar Hollywood commercial for someone's secondhand listing, without the inconvenience of spending a million dollars and actually going to Hollywood. To date almost 4 million unique commercials have been created and shared by letgo users. Check out the case study and four commercial trailers below I created with my own products to show how the app works.
