When you’re ready to mail that quilt to your swap partner or to your niece for Christmas, box it up at home and use USPS.com to pay for and print the shipping label. You’ll save a little cash by paying and printing the label out online, you can save the mailing address in your address book to use again, and you’ll automatically get free delivery confirmation. You can also choose to have the delivery confirmation emailed to you! Save time, save money. Smart!
