Thank you for your feedback. We do our best to advertise on the product page that the face plate is sold separately. We typically do not include the wall plate as there are many instances where the single gang face plate couldn't be used and would add extra cost for something that gets discarded. If you have any more questions or comments please reach out to our Customer Satisfaction team at customersatisfaction@lutron.com, or call us 1-844-LUTRON1. We're here 24/7, so please call us any time!
