If you were a Kickstarter, where do you get the pre-sale code?

I remember getting one for the 2017 and 2018 tours, but I can’t find anything for the Bubble Tour. Does anyone know what the code is? I’m in Knoxville and I plan on going to the show that’s coming up on 1/24

If you scroll down to the one of the Kickstarter’s update and find the Time Bubble Tour section, you’ll find the code.
