Someone suggested that he could sell 10 boards minimum or 25 minimum so people can organize group buys. I think this is a good option for both burnin and customers.
This is a good idea, releasing Burnin from burden of dealing directly with customers. If 25 minimum is too small he can raise it to 100, it will be no problem for a group buy to organize with usual (up to 10%) organizer fee instead of high reseller margins.
I don't think its that easy. I think there is a contract between seller and reseller, so that this will not happen... The reseller will not be very happy if the manufacturer directly sells to the end-customer...
