Once logged into your account click on "Order History" on the left menu or by clicking view under "Recent Orders" on your account dashboard. Each order you have made will be available from these pages allowing you to view their status, track them or even download or print order confirmation, sales invoices and tracking information.
Each shipments tracking number will directly open and track the package on the assigned courriers website, the same for the shipment email that is sent to you from the shipping department.
