Pricing for this show is extremely weird. Not sure what is affordable to you, but there is 95$ (per part) tickets for most of the shows, as someone has already pointed out. I know even that may seem steep since you have to x2 (per person) but it's important to look at it as 95, not the full amount, because you are essentially seeing two full plays after all.
I have seen people manage to get 40$ tickets while lurking the ticket thread on here. This is pretty rare though. I feel as though you'd have to check the boards here religiously, as well as ticketmaster. You'd also have to be pretty flexible on days.
Probably your best bet would be to enter the lottery, along with the person who you would take (you should each enter yourselves). Assuming you BOTH also choose to share on social media (currently they let you share on twitter and facebook), that's a 6x chance in total. However, I've been trying my luck for months and nothing, so I'm not sure how great even that is.
