The Prices tab is where you create the selling price list for the self operation tour. When you enter the tab for the first time, you have a wizard which you can use to define the number of seasons, the different price components, board base, and supplements.
You have to create the selling price list for the entire period of the tours’ operation with all the different dates (and not only for the first tour that you are now creating). Once the price list is created, when copying the tours for all the departure dates, the prices will be copied as well and each tour will be priced according to it’s departure date.
