We don’t, unless it’s alot of food. So much food in fact that the equivalent sized package would cost more than $10.50 for USPS to take 3+ days to deliver.
I love USPS but this whole thread makes people look like they’ve been huffing markers all afternoon.
Not just same day, same hour. That 1/3 cost comes with a 50x delay.
They don’t unless you have a good contract with them and even then it’s dependent on zones and package size.
Fun fact: USPS acknowledges that our US territories are domestic while UPS and FedEx treat them as international. So its a little more of a chore and cost to ship to Puerto Rico and the like through anyone but USPS from the 50 states.
