TodayTix is a no brainer
It was very easy to choose your seat from the map and book. I've compared websites and they are the cheapest at least that I've found. I highly recommend the insurance for $4 extra per ticket it's a no brainer. You have until the day before the performance to cancel for any reason and recieve a voucher. Super simple and I received the ticket immediately into my TodayTix account in the app.
