The service is still operating.  We've done stiff business the last couple weeks as Bitcoin exchange rates have been high.  I recommend that new customers do just what they'd do with any Bitcoin service they haven't used before: try a small transaction first to make sure everything works to their satisfaction.

I've had a couple customers do a $500 transfer for their first try and then find out that Amazon doesn't like their account for some reason.  They spend a few days working through Amazon's machine before they can get their funds.
