Looks like the group buy gives you 15% off (Normally $149.95 but now $127.46), free shipping and you get to be part of the first shipment of them. Use the code stated in their post above (I would assume in their email too but I didn't get one from them announcing the release yet...though I was signed up on the group buy).So how does the group buy work? I got the announcement in an e-mail. What's the price now as opposed to what it will be?
