Cost in thank you mail

Hey their,

This is my first message.
I want to set up our service using Appointment Hour Booking which is so great system.
My question is I want to put price in thank you mail automatically.
I have two menu which is different price.
I want customer choose one or two menu and send thank-you mail after appointment with the price.
I could not find the function to put price in thank-you mail.
Please tell me how to put price in thank-you mail if possible.

Thank you!!
Masa
