There is a coupon, you can earn if you are a superhost for 4 terms without a break. Not sure how much this may be where you are but for instance it's a £100 discount in the UK. It's not a lot but it is something. While hosts do not have priority in booking, i'm always delighted when a host books my space as they know what it is like to host, and have so far had people truly respect my space, appreciate my hard work, check and follow all the rules and leave positive feedback.
