I have a question about giving a couple of tees away as a means of promotion. I just had my first set of 8 tees printed up for an event this weekend. I'm not formally selling anything at the event, but this is a place where my target consumers will be in large numbers. My plan is to wear a shirt and give one to a friend to wear during the event and talk to people and pass out business cards. I know a couple of other people who will be attending also. Is it beneficial to give them tees for free as a means of promotion or should they pay for them?
