I was a bit surprised that Shelley Peterman Schwarz—who shared some really great holiday tips and is clearly computer savvy—missed one bit of advice. The U.S. Postal Service now provides convenient ways to use their services without going to the post office. At usps.com you can print a shipping label and pay for postage (and you get a discount on postage when you use Priority Mail). If you print an electronic shipping label and use Priority Mail, you get Delivery Confirmation at no charge. You can even order stamps or schedule a carrier pickup online.
