If you've opted to have your purchase sent directly to your house (or a friend/family's) you can easily track your package via UPS. Once I send you your tracking number follow the enclosed link to see where it's at.
If you want to be informed of it's progress instead of checking the site, you can opt for automated email updates by following these steps:
Address an email to: firstname.lastname@example.org.
Add your tracking number in the subject line. (If you need to track more than one package, keep the subject line empty and enter all of your tracking numbers in the body of the email.)
You'll be notified of your order's delivery status as it makes its way home.
