UPS website just updated my shipping status with these two items:
    07/21/2014    8:19 P.M.    Your shipment was not processed by brokerage and has not cleared customs. This has caused a delay. / Your package was released by the clearing agency.
Shenzhen, China    07/21/2014    8:15 P.M.    Your shipment was not processed by brokerage and has not cleared customs. This has caused a delay.

Still says it will deliver tomorrow but I find that hard to believe now.
