How can I add pricing tiers to bookings

Since price tiers don’t work with bookings, I would like to add a custom attribute to the listing that when the customer checks it off it will be added to the grand total.

Hi,

You can use price extras for that. Users will be able to choose different options and the price will be recalculated

I need only one option to be chosen and it to override the original price. For example
(Original price is 100)
Extra 1: 200
Extra 2: 300
If extra 2 is chosen then the total price has to be 300 instead of 400.
