Can I cancel my order if I change my mind?

Unfortunately not. Tickets purchased from See are strictly non-transferable and non-refundable unless the event is cancelled or moved to another date.

However, See do offer an ethical resale service for tickets which have been purchased through See.  Fan-to-Fan allows customers to resell their tickets at the price they paid or less. It is completely free for sellers to list tickets using Fan-to-Fan.
