For the US Postal Service, today (12/15/15) is the last day that standard shipping services will make your package arrive in time for Christmas. In the freight world, similar deadlines are here. Standard LTL service can take 5 - 8 business days from coast to coast, which means that shipments headed to retailers, wholesalers and distributors who want to make that product available to buyers in time for Christmas must be on trucks soon.
