<div dir="ltr">Have you guys heard of the "virtual" group buy PCB site: OSH Park <a href="http://oshpark.com/" target="_blank">http://oshpark.com/</a> ? they take care of combining the orders into a large panel and then depanelling and shipping to individuals. Thier volume of orders is so great that they send a new panel to the factory daily.<div>
<br></div><div> Shipping is included in one price @ $5 per sq. inch for 3 boards. Once you upload gerber project it can be shared publicly for anyone who wants to re-order. OSHpark might be a low overhead way to share Helmut's board.<div>
