Often, though, you don't have to wait until the very last minute. I've seen and posted about many premium location seats that have been available on Telecharge for $229 the day before the performance. It's a very random process, so just keep checking Telecharge. Also, many times they'll release $229 rear side orchestra seats (wheelchair/companion) first, say 3-5 days before a performance. If you purchase one of those, and then they release much better $229 seats closer to the show, I believe Telecharge will allow an exchange. You will probably have to purchase the new seat, and then they'll refund the old one, but, in the end, it will come out to an even trade.
