No one is going to be selling outright for less than $300, it's just too new. However if you put in a bit of effort you should be able to get a pretty good deal. I would recommend buying from GlobalGolf with the following steps:
1. Log in to your rewards account, if you are not signed up do so now: http://www.globalgolf.com/account/rewards/ (Seriously, it's awesome)
2. Trade-in your old driver, they will give you 40% extra since you are buying a new club. You will also get 1 reward point for every dollar your club is worth.
3. Buy the new driver at $300 minus whatever you got for trade-in credit. You will get 900 points for the purchase. You also get free shipping and their playability guarantee, I've changed my mind twice before no questions asked, even though I played the club.
4. You will likely end up with over 1,000 reward points. Use this to get some free gifts (gloves, balls, etc.)
So you still have to pay full price, but you'll get a better value on the old club and you'll get some free goodies with the purchase. It's the best I've seen if you can't wait until the price drops.
