As a general rule, tickets are not refundable. However, venues selling through MyBoxOffice.US have different refund rules.
Once a refund request is received, MyBoxOffice will attempt to get an approval from the venue on your behalf to process the refund. Once approval is received a refund equal to the face value of the tickets will be issued.
REFUND OF SERVICE FEES:
Under normal circumstances, services fees are NOT refundable.
If a refund is due to an event cancellation or due to a venue-initiated change (like an event rescheduling), service fees will become refundable.
