Holiday season sale ends 3rd Dec 2013

Vegas Pro for $419 USD 

Vegas Pro Upgrade for $140 USD 

I'm pretty sure you can buy a brand new copy of Movie Studio 11 for $35 USD  and then use this offer to upgrade to Vegas Pro 12 for $350 USD . This gives you Vegas Pro for $385 USD, which is a significant discount from the $600 USD standard pricing. I know someone who did this last time the offer was on and it all went through fine but I can't guarantee it will work this time.
