Hi Oracle, I am glad to hear your were satisfied with our service. You said you didn't know how we make profit on this deal. The fact is, we nearly have no profit on it. But we are happy to do it because it is a very good service for OSHW guys.It is much appreciated if you can choose the Open source option. That saves money and make other guys be able to share your design. On the other hand, we can make some nice designs into kits and retail. That's what we called: Propaganda Kits service. . http://www.seeedstudio.com/wiki/index.php?title=Open_source_Kit.
