The advantage of buying locally is the instant availability of need items. Some sports stores, including All-Star Sports do carry some referee items. Others, like Dick's, do not except for generic items like whistles.
For PWSRA we recommend one of our former referees who is also a sales rep for referee uniforms.

Klaus is a sales rep for Official Sports, the official supplier for U.S. Soccer. He can have items shipped in 2-3 days. If you buy: Use the Official Sports website to find the product numbers then contact Klaus. He will give you a PWSRA discount (not available on the website) and free shipping.
You can order directly from Official Sports from their website but do not contact Klaus if you do as you are ordering from the company and not a sales rep.

Many options are available for purchasing uniforms. With all purchases, allow enough time before the season to purchase. At the start of spring and fall seasons is when many suppliers temporarily run out and have items on backorder.
