Starting and Minimum price explained
The starting price is the price that will be asked for a declining-price-ticket when it is first listed. It represents the maximum amount that you want for your tickets.
The tickets will first appear at this maximum price and, unless they are purchased, the price will decrease linearly every day until the minimum price is reached on the date of your choice.
The tickets could sell at any price between the starting price and the minimum price. viagogo automatically drops the price on a daily basis.
