Wayne, the reason for limited responses may also be that some school districts may have "preferred" (or, mandatory) suppliers for things like shirts.

I know, for example, that my college prefers that teams go through the campus bookstore for shirts. We have to at least give them the opportunity to decline, or beat competitors' pricing. Doesn't mean that we can't go elsewhere, just that the bookstore has to know about it.
