Dec 10, 2017 Holiday Shipping Deadlines The following are the USPS holiday deadlines for items to arrive before Christmas. This is for the US only. International orders placed now will probably not arrive in time for Christmas. If you need items in a hurry, we do offer Priority Mail upgrades at checkout (US only). The dates are from the USPS website; we make no personal guarantees. Most all items are shipped USPS, however, heavy items may be sent UPS (which has similar deadline dates).
