If you have selected UPS Standard shipment; your delivery (or attempted delivery) will be made between 9:00am-6:00pm local time on the day of delivery.
The shipping timeline will depend on your location, and is based on estimation only. There is not a guaranteed time for the UPS Standard service, however generally this is within 4-6 business days. If the delivery address is local to the office your package is shipping from, it could be as fast a next day delivery.
For a guaranteed timeline, UPS Express shipping should be selected.
