Let's assume worst case scenario BFL takes our money and runs. Is there any chance we can get our money back in that situation? Through any intermediary?
If things go wrong, BFL will declare bankruptcy. Then the remaining assets will be distributed to creditors by a trustee, if there are any assets remaining. Your chance of recovering your full "pre-order" in this event is extremely unlikely.
There is a reason that the FTC Consumer Protection division has "prompt delivery" rules. Know your rights. If the delay is longer than 30 days or indefinite, you are to be promptly refunded unless you have agreed that the delay is acceptable.
If you are having issues obtaining a refund from BFL, you may file a complaint with the FTC here:
