Polo T-Shirts for FRC

[TDav540]

While we were at Championships this year, I attended Team 1902 Exploding Bacon's Conference this year on marketing a team. One of the points the presenter made was that 1902 uses polo shirts for more formal events such as presentations and community outreach. This idea truly struck a chord and now I am pursuing polo t-shirts for my team, TALON 540, for the same reason.

I saw many teams with polo shirts attending the Championship, and I was wondering where you guys get your polos printed or made well for a relatively low cost. What website or store do you get your shirts made? Any tips for making a great polo would also be greatly appreciated!
