Oh they absolutely work overnight. Mine just got arrival scanned, customs imported, etc. it should get processed and shipped to MN here shortly and since I'm having it held at the CC I should get it asap in the morning.Do you know if Kentucky would depart the order overnight? For me its 12am in California, does their facility work during the night? Or is everything left for the morning? Not sure how UPS works, but you're a genius when it comes to it!
