Thanks for the feedback Kirkotoby! The way express works is if you drop it off by their cutoff (which varies per post office) the postal system will get it to the destination by 3:00pm either overnight or second day, depending some details about destination post office's (mostly when they get their mail from the sort facility). My cutoff is noon pacific which means I will get all orders placed by then to the post office in time for their cutoff. If you place an order with me by noon pacific there is an 80% chance of the USPS promising it next day by 3:00pm with the remaining 20% chance of getting it the second day. USPS performance is outside my control but they meet their promise 97% of the time.
