No, we are unable to exchange tickets or refund the difference if the price has changed. As we operate on the secondary market, this also means that we are a live market. This means that the prices may change if the seller decides to raise or lower the prices, as our sellers have full control of the prices on our website. Most of the tickets that you see are listed by different sellers and we are not able to cancel any orders as our Sales Terms have a "all sales are final" policy which is agreed upon when purchasing tickets.
