I guess we'll start to see in a few weeks.. I have the cost of a moderate house riding on KNC and the cost of a compact car riding on BitFury. I bought a crapload of BFL stuff, too, but it's likely to be worthless by the time it's delivered.
I put a refund request into BFL, no response. Of the three companies (BFL, KnC, BitFury) BFL has been the least responsive to all email I've sent. The email I've sent to either KnC or BitFury has been answered in under a day.

Can I ask you when did you ask for refund? I am thinking to do same thing with one of 2 orders.
