Anyone got a good source for printed t-shirts?

Black - check with your local law enforcement uniform store(s). They probably have piles of t-shirts with "security" printed on them, or can get them quickly. "Security" t-shirts used to be a standard product at Steve & Barry's as well, before they went bankrupt.

Thanks . . . unfortunately I have no time during normal business hours to track such a place down or actually visit one.
Will keep it in mind in case someone else ca.
