If you want to have the earliest RD possible and want peace of mind, send out your package today, Friday, Jun 29, by commercial courier Fedex/UPS/DHL so you can track online by the minute.
The service is called "Next day Air" or "Overnight". Please remember it is neither "Saturday Delivery" nor "Next day air Save"
This package will be delivered by noon on Monday, July 2, if nothing goes wrong.
For couriers, they only count business day, and Monday is the next day of Friday.
You should list both street address and PO BOX so the receptionist knows what to do.
If you follow my advice, most likely you will get a RD of July2
