DRS - box office or half-price ticket booth for Tickets?

I don't know exactly how this works, but if I want to get tickets for DRS (or any show for that matter) on the day of (if that's possible) would I be more likely to do so by going to the box office for cancellation tickets that morning or going much earlier that morning to the half-price ticket booth? From what I hear, corporate tickets that are canceled are NOT sent to the HPTB and are good seats that you can only get at the box office.

Some one help me out, please!

You can also wait for cancellations. These are sold one hour before showtime. These are usually the house seats that won't be used at that performance and are normally the best seats in the theater.

There was one time that I went to the TKTs booth and saw DRS (35% off) on the list. Since my mom thought it was a bad deal, she didn't want to buy the tickets. We saw La Cage instead.
