Discount codes for 1776? Or TKTS

I'm going to NYC for Veteran's Day and want to see 1776 -- does anyone know of any discount codes? Or should I just hold off and get the tickets at the TKTS booth? I'm following the app and it's been listed nearly every day, but I am going on a holiday weekend and will probably go to the Saturday matinee. Should I just suck it up and buy tickets in advance?

Also thinking about Leopoldstadt for the same weekend, maybe Thursday night, but I'll only need a single ticket for that which is easier to get. I'm hoping to see 2-4 shows!
