No, it was most definitely BTC values. Taken to full decimal places and no rounding, 8.088% restocking fee. If I make the .0005 transaction fee my responsibility that becomes 7.8882%. The total amount I am short, again without rounding, is 0.016485898. This is BTC in, BTC out. I even double checked my emails with the blockchain.info transactions to make sure the amount was correct. I'm not complaining, just warning that people should double check.
They said it was whatever your payment method. Most people paid in BTC (either directly or by converting USD). I didn't know there was even an option to pay directly in USD on this one but maybe there was. So if you paid in BTC and didn't get the same BTC back (less "restocking" fee), you have a valid complaint.
