Someone please help. I'll give as much info as I can without saying too much.
According to tracking, the pack was sent yesterday morning via 1-day priority express. The scheduled delivery date was today by 12pm. It's now past 3pm and it hasn't shown up. My regular mail has already came - previous express orders have come with my regular mail. The last tracking update said the pack arrived at the usps origin facility yesterday, from the state it's being sent from.
I don't understand why it didn't come today. Should I be worried? Has this happened to anyone else before? The product being sent is extremely small and weighs practically nothing.
It happens all the time. Don't panic and check tomorrow.
Edit: I've even had them say it was delivered but show up the next day.
