Keep an eye on Amazon. I bought my copy back in June of this year for $179.99 and free shipping. This is the full retail version. I parked it in my wish list and checked the price daily for about a month. I was surprised how frequent the priced changed up and down. When it drop to 179, I grabbed it. I checked the price a few hours later just for kicks and it shot back up.
