You gotta work for this one but it's pretty cool. Especially if you are a Starbucks and "Project Runway" fan.
My favorite designer in the last season of "Project Runway" was Mychael Knight. He is now doing custom t-shirt designs for Starbucks. Every day at 10am PST, they are giving away 250 shirts. You get to punch in the components of your favorite drink and then your drink shows up in an artistic way. You can then order it on a free t-shirt. They are giving away 250 a day until February 28.
It took me a few tries to get in. The site actually goes live between 9:55am and 10:00am. I opened three browsers and kept refreshing them. Normally, there is a message at the bottom of the screen that says they are out of shirts. Right around 10am, the message goes away. That's how you know you got in. I would practice creating the design a few times first so that you can do it really fast.
I hear they also send you a free drink coupon with your t-shirt.
