you are referring to a standard US order with standard shipping which is sent via Royal Mail and then handed off to USPS. there is NO tracking on these orders, and therefore, it imakes sense in your case. on the 19.95 deal, they are sent with expedited shipping, and therefore sent with a courier service. less chance of them losing it this way, although i must admit, i have made many orders via the US site, and have never had an issue with the standard shipping.
