Postage rates are changing for domestic and international mail.
Changes include:
The Phillips Hall Post Office has "Forever" stamp booklets that contain 20 stamps. Purchase them before we close on Friday at the current 42-cent price (or $8.40 for a booklet of 20 stamps). They are valid "forever" at the current first-class rate.
Certified mail, insurance, delivery confirmation, and money-order fees are also increasing.
