We ordered our shirts from
here. They are a local company and we didn't pay for shipping, so I'm unsure of shipping price and speed.
The cost was about $7.20 per shirt for a single color, front and back, screen print for more than 48 shirts. Add tax, shipping, and screen print charge, and it will cost around $480 for 50 shirts. They accept high resolution Freehand, Illustrator, Photoshop, EPS, PDF, TIFF or JPEG images.
Here is the proof of our shirt. Our shirts were ready in 3 days, but I'm sure they could be expedited by request. (Be aware XXLs and larger cost more. Personalization is also available.)
All U is also responsible for
screen printing our bumpers, which look really nice. I'd highly recommend All U to anyone. This is our third year of using them, and the shirts are great.
Edit: Yes, we know the logo isn't the correct usage according to
FIRST but it was a mistake that will be fixed for next year.
