last minute discount Highlighted

Hi everybody ! 

My name is Clémence I work in a small guided tours agency in Lyon, France.

I would like to know if there is a way to highlight a discount ? We would like to try last minute discounts for tours that don't have a lot of reservations, but we would like to highlight the fact that there's a discount. With a red tag or something like that.

I've been trying to add a special pricing rate, but it just changes the price shown without  a special message saying there's a discount (I've added 2 screenshots, one with the normal price, one with the special pricing rate).

Does anyone know a way to do it or a little hack for that ? 

Thanks a lot for your help ! 

Best wishes,
Clémence
