Let's see ... 50% early bird discount from an already low price (500 for 2 days, 250 for 1, discounted to 250 and 130 for the next two weeks so act fast), a full version of Visual Studio Professional, a full version of Expression Web, the DVD set from Tech Ed 2008, and a coupon for $100 off a DevTeach registration. That's not counting the eval versions of VSTS and Expression Studio. Holy Smoke, this would be a cost effective thing to attend if you didn't even go to any sessions! But the sessions are listed, and they are good ones. Need to know how to build a real application in WPF? Use the ASP.NET AJAX extensions in your web app? Use controls and styles in Silverlight? Lock down your SQL server? This is the conference for you. Local, inexpensive, timely, ... and a bag of goodies.
Plan to be there. And that includes doing a little reading first ... these sessions don't start at "what is this Visual Studio you speak of?" so there's a resource list to get you ready to attend.
