Thanks for reaching out!
Nearly every listing on our site is listed by a professional ticket agency-around 99%. Once you place an order on our site you are back by our Buyer's Trust Guarantee; that guarantee states that your tickets will be valid, they will be delivered in ample time, and, we would source a replacement/s of equal or greater value if there was ever an issue with the ticket/s. The latter point I can assure you is extremely rare. We take pride in our customer service and will make sure that you are taken care of.
Please reach out to us by email at firstname.lastname@example.org
or by phone at 845-538-4567 if we can assist in any way.
