UPS website did not update that it received the actual packages until 1/5. That tells me Ancestry didn't give them physically to UPS until Monday, 1/5.
The initial order was sent on 12/23 to Ancestry. With 2 holidays and 4 weekend days, Ancestry was still 2 days late getting it to UPS for delivery. It should have been here on 1/2. And UPS does deliver on Saturdays.
