Holiday shipping deadlines sneak up quicker than we all anticipate. We all know the mad dash to order things on Amazon Prime just in time to wrap it on Christmas morning. If you're sending things to loved ones across the country or even across the globe, here are the days you need to keep in mind:

Domestic Shipping --

First-Class Mail Service: Dec. 20

Priority Mail Service: Dec. 20

Priority Mail Express Service: Dec. 22

USPS Retail Ground: Dec. 14

International shipping varies on the country but usually for standard shipping, gifts need to be in the mail by December 8.

Keep in mind that your local post office hours vary depending on location and will be closed on Christmas and most likely close early on Christmas Eve.
