Domestic mail weighing less than one ounce requires a 49-cent stamp ($0.49). Postage for other items varies depending on size, weight and—in the case of international mail—destination. Postal service prices are subject to regular changes. To find out updated prices, contact your local post office or visit the U.S. Postal Service on the Internet at postcalc.usps.com.
The U.S. Post Office can also send packages, by air or surface transport. If you need something to be delivered quickly and need to track it, then the courier services FedEx or UPS are usually better options. Both offer domestic overnight and 2 to 5 day service worldwide. The faster you want your package to arrive, the more it will cost! U.S. mail is delivered Monday through Saturday, except national holidays.
