I'm a coach and director for a major youth football program and a booster/team dad for baseball. I've been doing this for many years and always used a local screenprinter or sports shop for our jerseys, warm-ups, sweats, etc. I found MyLocker.net online a year ago and I'm so impressed I had to write a review.
Their pricing is excellent, but that's not why I love the place. They are crazy good at handling everything for our team orders so I barely have any work. I used to run around like a nut to get the design and samples and proofs and pricing and all that. Now, I deal with one company who does it all. Nearly everything we've done has been perfect, but when a goof happened, they took care of it right away.
More importantly, their site basically makes all the individual spirit items and unique requests fun instead of a pain in the rear. You've got to go to their site to see what I mean, but you can pretty much design anything you want in a few clicks and it shows up at your door by FedEx. We just started putting a link from our team website and facebook page to our mylocker store so everyone can create their own.
I would definitely recommend mylocker.net.
