You mean the RazorDog sales? That sounds about right. For those interested in the K712 I wouldn't worry too much about the deadline though. I got mine from Brian at RazorDog for $385 with a previous coupon code and most likely head-fi members will be able to get them for around that price at any time. Just shoot him an email, he's a great guy. Authorized dealer, awesome customer service, and shipping is fast & free. I've bought several cans from Brian and I've never paid close to list price and its always been a great experience. Highly recommended.
I guess I have found a place to buy my toy(s) next year! xD
Either way, I don't own a K712 Pro, but I do have a K702/65 which is said to have a similar sound signature. Loving it a lot!!!
