Thanks guys. This helped a lot.
We have a set of 3 brothers in our team and their mother happened to have a button maker we could use so I ended up buying supplies for these online. We're having each kid pay $3 to buy their own shirt. (up to $6 if they can afford it.) I found a great local business who was willing to do it for just the cost of the tee shirt. It's all beautiful screen printed stuff too. With the left over money I bought little flashing octopi to write our team name and number on and give out to each team. We're also going to use our photo printers to make copies of a team photo to give out. We're an art school so they're really good quality epison printers. For this year's competition we're also going to do trading cards with our robot's weight and stats on them.
