Can customers track their shipment during shipping? Tracking codes

If you order via priority or Priority-express, or rtrackstandard (standard with delivery confirmation -- only for bubble mailers/parcels), and include the customers email, we automatically send them tracking information via email when the order is processed.  Standard first class mail does not currently have tracking.  That is partly why it's so inexpensive.  Remember, UPS or Fedex charges 15.00 or more for any package (which of course includes tracking).  Your most economical method for sending a package with tracking is USPS priority mail (about 6 dollars).
