I got it an hour before the show once, on a Saturday afternoon, and was in Row A of the balcony.
Their discount code offers $28 balcony seats, which is essentially the same price as rush and you can choose your own seats and not have to worry about lining up. I linked the code below, but they also have people all over Times Square handing out this code.
And the view from the balcony isn't bad at all. Definitely worth it, and worth seeing this wonderful show before it closes.
