T-Shirt Give away

My app should be ready for Apple approval soon. It's time to reassess my marketing position and get ready for release in approximately 3 - 4 weeks. I have been monitoring the app scene and have decided to forgo adding Admob to the free version. From what I have learned, it doesn't add to the bottom line. Word of mouth is what you want to make happen. I am going to try some grass roots methods to get people talking. I went to a street festival concert last night. One thing I was reminded of is that people will do anything for a free T-Shirt. I am going to do a T-Shirt give-away. T-ShirtPros.com prints custom jobs or I may go the CafePress route. Coffee Mugs will also be a good office related giveaway.
