Post Offices and postal retail units with integrated retail terminals (IRTs) will receive price change diskettes in the same manner as all other IRT software updates. Each office must install the IRT update after the close of business Saturday, May 12, or Sunday, May 13, as appropriate, or before opening for business Monday, May 14. Offices that do not receive diskettes with the new prices and fees by Thursday, May 10, should contact their district IRT coordinator for guidance.
