How can I update my minimum price? 

The minimum price is provided to the owner as a safety net to ensure booking don't go below the price after the use of any discounts. You can update this at any time from your owner login by using the help video below. It will update instantly. 

To help you understand. If you set it at £500, no booking will ever drop below this value. If you set it at £1, it's won't ever be used as your other pricing will always be higher. I hope this helps.
