For your security we do not have access to your payment information so we cannot exchange photo ops between different talent or teamups online. We would have to refund the one photo op ticket and you would need to purchase the new one. Please keep in mind our refund deadlines which are displayed prominently at the top of our online store. We are unable to process refunds after that time.
Alternatively you can always use your photo op as credit towards the purchase of a new photo op at the convention as long as the session is not sold out.
