You don't take into account us who have already paid these people money to make Avalon chip based miners and now are forced to take a 30% loss in converting our old orders to these new boards.
He is generously offering to refund you a proportion of the money that you spent on a non-refundable deal - and you are bitching that he is somehow in the wrong?
Looks like we have a different definition of "generous".
It's called damage control. The Avalon based boards became a total loss already some time ago, hence "forced" to get a refund from group buy and "forced" to convert my order to BitFury based one to lose _less_ than the 50% already stated to be gone.
But hey, if it's bitching in your definition to ask why these new boards are priced so high that even these are a losing proposition... be my guest.
Fact is, someone is price gouging on these new boards, and the question now remains if the idea is just to squeeze as much extra money out of us pre-orderers as possible.
