The U.S. Postal Service has introduced another new product: the padded flat rate Priority envelope. The new envelope is for domestic shipping only. It is not available at Post Office locations; it is only available through USPS.com/shop for home delivery.

There is no charge for the envelopes, whose dimensions are 9 ½ by 12 ½ inches.

The new envelopes are ideal for sending gift cards, musical greeting cards, all types of merchandise, jewelry, candy, books, clothing, stationery and virtually anything else.

As with other flat rate envelopes, “if it fits, it ships” anywhere in the country for $4.95. The envelopes receive two to three-day delivery, free package pick-up, and advantages like no surcharge for fuel or Saturday and residential delivery.

As an added bonus, shipping labels printed with click-n-ship from usps.com receive free delivery confirmation service (a 70 cent savings).
