They offer No refund until January. None.
They have your funds, if they f**k up, they promise to return monies, but have no third party to guarantee it.

None of these competing companies have met the strict requirements of a third party totally independent Issuing Bank and Payment processor.
None of these competing companies have the backing of Paypal, except Butterfly Labs, of which this is starting to become a very welcome avenue for disgruntled BFL customers.
None of these competing companies are assuming the risk involved with a credit card payment processor and promising the buyer protection from these independent third party bodies.
None of these competing companies are offering any real buyer protection (and BFL are trying their damnedest to change their terms and wriggle out of the responsibility).
