Sending parcels and letters in the US is a relatively straightforward process. The most common method is through the United States Postal Service (USPS). The USPS offers a variety of services for sending mail, including First-Class Mail for letters and postcards, Priority Mail for packages, and Priority Mail Express for overnight delivery. To send a parcel or letter, you will need to take it to a USPS post office or use a USPS blue collection box. Use the USPS website to find the nearest post office or collection box to your location. Additionally, you can also use private couriers such as FedEx and UPS, which often provide a wider range of services and faster delivery times, but generally at a higher cost.
