According to the USPS, for mail traveling between Memphis, Tenn. and Minneapolis, Minn., delivery time can vary, depending on what delivery service is chosen. The United States Postal Service has priority mail express, priority mail, first class mail, standard postage and media mail.
Priority mail express would arrive at the specific destination the next day, per the USPS. To save money, the USPS states that priority mail will deliver between two and three business days. First class mail is often the best and cheapest option if getting immediate delivery of the mail or parcel is not necessary, according to the USPS.
