Current 'O' Discounted Tix?

My sister is going to Vegas in late May and asked if I knew of any Cirque 'O' tickets at a discount... I know I frequently used to get emails from MGM Mirage announcing sales on their Cirque tickets, but haven't gotten any of those for a while.

Does anyone know if there are any current specials for 'O' or perhaps one of the other Cirque shows? They are kind of on a tight budget so I'm sure they could be persuaded to see another of the shows if the price was right.

Thanks!
Jennifer

You don't see many discounts for 'O'.

Thanks Greg. Discounts for any other Cirque shows going on right now? They are flexible with what they see.
