Introduction

The USPS (United States Postal Services) module is used for real time shipping cost calculation. When you activate this module for your store LiteCommerce can fetch real time shipping quotes from USPS servers through shipping webservices. The rate calculators provide quick and accurate information on the cost of mailing packages with USPS. This information is taken into consideration while calculating the total shipping cost in the order total. Before using this service, you should get an account with USPS.
