From the folks at Endicia, a reminder re: the upcoming mailing / shipping USPS price changes (note the price of a 1 oz. first class letter, one of the most common types of mail will NOT change:
April Price Change
On April 17th 2011, the U.S. Postal Service will be changing prices for non-expedited mailing and package services as well as extra services. Here is an overview of what will be affected by this price change:
Below is the change for First Class and Parcel Post:
Postcards, letters, large envelopes (flats) and small packages can be sent using First-Class Mail®. This service is ideal for sending personal correspondence, handwritten or typewritten letters, and bills or statements of account. It may also be used for advertisements and lightweight merchandise. First-Class Mail prices are based on both the shape and weight of the item being mailed. For items weighing more than 13 ounces, use Priority Mail.
The following are descriptions for each classification of First-Class Mail:
Mail books, sound recordings, recorded video tapes, printed music, and recorded computer-readable media (such as CDs, DVDs, and diskettes). Media Mail can not contain advertising except for incidental announcements of books. The maximum weight for Media Mail is 70 lbs and no more than 108 inches in combined length and girth.
Parcel Post pricing has been greatly simplified. Most of the price cells will not increase on April 17th, and some cells will actually decrease.
Use Parcel Post when sending small and large packages, thick envelopes and tubes containing gifts and merchandise, delivery to all US addresses-including PO Boxes and military addresses, Saturday and residential deliveries at no extra cost. Package can weigh up to 70 pounds and measure up to 130 inches in combined length and distance around the thickest part.
