Shortly after listening to Microsoft Adcenter Live on the ShoeMoney aka Net Income Radio Show, I came across the following offer code: 4CGXQSWGS58MCMD4
Please note that the offer is valid only through June 30, 2007 (midnight PST) while supplies last and for new advertisers only. In addition, the offer suggests you visit startadcenter.com/steve to get started but the URL doesn’t exist. Just thought I’d mention that.
Update: The link works now.
