Android Central

Have you been on the fence about the Nexus S?  Maybe this will get you to take the plunge.  Best Buy will be offering any version of the Nexus S (for T-Mobile, AT&T, and Sprint) for free.  The catch?  You have to sign a two year agreement (new line or upgrade) with the respective carrier.  The offer is good specifically from tonight at 11:00pm CST and August 3rd at 11:59pm CT.  Plenty of time to make your decision, right?
