"The U.S. Postal Service has a product a lot of people don't know about. That's because it's not available at the post office.
The envelope, whose dimensions are 9 ½ by 12 ½ inches, is for domestic shipping only and is sent to your home or office in packages of 5, 10 or 15 envelopes.
There is no charge for the envelopes and they are only available through USPS.com/shop."
"As an added bonus, shipping labels printed with click-n-ship from usps.com receive free delivery confirmation service."
