Reduced Day Seaats

Hi all, dont know if anyone can help. Just want to see if something is the same in NY as it is in London. Many shows do day seats in London, where front rows are reduced.
I just wondered if any productions did this in NY, coming over in feb 08. If so times to get there would be great help.

Thanks all
