I received this email because I purchased tickets online last year but I'm pretty sure anyone can use the code. Show this year is on 2 to 4 May.
Price drops after you enter code (e.g. from $20 to $16 for adult tickets). Price at door is $24.
Note, last year Ticketmaster sold tickets with 50% discount a few weeks before the show so you might wanna take a gamble that Ticketmaster will do the same this year :)
You can't bring dogs along - I don't get it either but I guess there are enough dogs inside the venue as it is!
Not sure about that, it looks unique…
