Had your eyes on a Nexus S but still haven't taken the plunge? Then it looks like that indecisiveness has finally paid off, as Best Buy has now knocked a full $100 off the phone for a limited time if you're signing up for a contract. That's from today until March 23rd, to be precise, and it seems that your local Best Buy doesn't even need to be a T-Mobile dealer for you to get the deal -- you'll just have to get the phone shipped to you. Hit up the link below for all the details.[Thanks, Kevin]
