just a note, still seeing people concerned about expiration date, this is no longer an issue. No where will you receive an email, or see a notice that they expire, was all fixed on website. Tickets do not expire, and offer goes till may 20th. I've purchased 2 sets, one for 2018, and one for 2020. Interesting note, if you order over the phone they ship them for free to canada, where as if you order online, you pay 20 dollars if you want them shipped.
Did you have to assign tickets names if you ordered them over the phone?
