You may have seen by now, but in Ken Davenport's blog (posted above), he noted that Sept 16 is the final day of "Broadway Week" 2-4-1 ticket offers, so they presumably want to get people in the door during its final weeks rather than close immediately.
It's not just the losing of money that makes this ridiculous but the fact that the 2 for 1 prices are astronomically higher than the prices at which tickets are being sold.
