Almost all teams give out buttons in the pits to hand to other teams. My friend suggested we use Badge-A-Minit buttons, so we designed them and made about 300. This summer I was on their website drooling over their Badge-A-Matic when I saw a contest. $100 gift certificate to a customer that uses buttons in a creative way. I’d say getting publicity through trading with other teams in a robotics pit is fairly creative. Plus we got James Kenedy and Jeb Bush to wear our button! They dedicated a portion of their website to us on their customer comments link, which you can see here
Who else here uses Badge-A-Minit products?
