first time booking discount on rover?

I had a guest ask me about a first time booking promotion discount with Rover. I just started hosting with rover after being with dogvacay for 4 years. As far as I know there is no discount, or Rover has never mentioned that for first time bookings...i know there is the link referral and give 20 get 20 or something, but it is not for first time guest bookings. so question is does something like this exist?
