There's a discount code for Kinky Boots, THM11 on Ticketmaster, but you'd be better off trying the $37 digital lottery and the $27 standing room first, then have TKTS as a last resort, considering there's a very good chance it will be on there this weekend. As far as Miss Saigon is concerned, you'd probably be able to score $39.50 rush tickets, since they're very easy to get. With Book of Mormon, there's a $50 digital lottery, a $32 in-person lottery, and $27 standing room. Finally, even Hello, Dolly! is a possibility, with $47 standing room, and, after those are sold out, $59 last row of the balcony tickets, which are really not as bad as they sound. So, all in all, you have a lot of options for shows on a budget.
