My order was sent out on the 11th. So this took a bit longer than normal. If you got guaranteed ship you are fine. I'd be interested to know what ends up happening.
Edit: Also bethpage was a little fucky for me on this order. Processed and departed the facility two times. But this has happened to me before, at a closer sort facility. Contacting usps about it wouldn't be that crazy. It might be just stuck in a delivery loop. USPS is inept after all.
