"Cannot ship to this address" errors

If you are placing orders late at night and getting a "we cannot ship to this address" error, please try and submit your order again a little later. The issue is that the USPS rate calculation servers go down for a reset between 10pm and midnight most nights and for some reason our backup flat rate is not getting applied by our shipping handler software like it used to. We're currently looking into the issue and hope to have it resolved shortly. Sorry for the inconvenience.
