Changing the discount of the flat

[Urszula0]

Hello, I'm new on airbnb as a host. I miscalculated the discount price for the montly rent of the flat. I would like to change it but there was one lady who asked to rent the flat for one month and she said she would come back to me within a week with confirmation if she takes the flat or not.

I would like to keep my fainess and keep the same price for her if she comes back with the discount before my change. 

I thought to send her a message ensuring that she would get the price that was offered to her today. But is it possible to do it for her , when there is a new % of discount from lets say tomorrow on?

Please, could you advice what to do? How can I secure the 'old' price for her?

Thanks you, 

Urszula
