I've got a website with the sole purpose of showcasing my web extension and I just cannot get the hero/statement banner to communicate what it is. The extension delivers to its users, the latest freebies, competitions and coupons, so the premise is money saving and winning stuff. The extension also eliminates the need to fill in forms as it has a form filling feature - but I really have no idea how to condense all this info into that banner.
