Hey @SusanEpstein! It's typically the event start time but all events are different and could possibly have a cut off time of 90 minutes after the show begins. This depends on the venue it's taking place at and the delivery methods available for the specific event. If there are Mobile Tickets for sale, the cutoff time can vary as some listings will expire 4 hours before while other events could cut off at 2 hours before. The cut off times vary depending on what event it is for so if you have a specific concert in mind, just let us know and we can provide you with all of the correct information pertaining to that event!
Hello @Jschn549! The best way for you to do that is to reach out to any one of the Moderators here on our Community, and we would be happy to look that up for you!
