Delivery Status 3.8 - Widget displays order status for many delivery services. (Free): "Delivery Status... Can't wait for your packages to arrive? Don't waste your time checking the site constantly, just open this all-in-one delivery tracker and enter your order number or tracking number. The status will update automatically for you, and even count down the days! It also works with Growl to give you pop-up message, email notifications, and more, whenever your package status changes.
