Reads current USPS holiday shipping deadlines from usps.com. Muse can check send-by dates for Ground Advantage, First-Class, Priority Mail and international services, see days left, and name the cheapest service still on time for a destination, country or APO/FPO ZIP.

Example request: "If I ship a Priority Mail box to Alaska on the 18th, will it get there before December 25?"
