@package_name@ provides a simple yet flexible way to maintain a set of custom shipping rates based on the total value of the shipment.

@package_name@ is based on 2 principles: Service Levels and Shipping Rates.
Service Levels
Value-based shipping rates are specific to service levels. E.g. the shipping rate for 'Ground Service' differs from the '2nd Day Air' or 'Next Day Air' rates. Hence, service levels need to be defined before shipping rates can be entered. Maintenance of the service levels is through the
Service Levels Administration pages. As said, services levels need to be defined before shipping rates can be defined. Conversely service levels can not be deleted as long as there are shipping rates for the service level. However, service levels can be renamed at any time. All changes have an immediate effect on life systems.
Shipping Rates
Shipping rates can be defined after the service levels have been entered. Maintenance of the shipping rates is through the
Shipping Rates Administration pages. Shipping rates a specific to a service level, the location of the destination and the value of the shipment. Rather than listing each possible location in the shipping rates table, @package_name@ uses the concept of regions.A region is defined by a combination of Country, From zip code and To zip code.
- The most global region is the world, which is a combination of no country and no zip codes.
- Following the world are entire countries, which are defined by selecting the country while leaving the zip codes blanc.
- Regions within a country can be defined by choosing are range of zip codes, ranging from the From zip code to the To zip code.
When selecting services and rates, the RatesAndServicesSelection operation compares the value of the shipment against the values of the From value and To value fields.
- RatesAndServicesSelection selects shipping rate if the package value is between the From value and To value.
- RatesAndServicesSelection also selects shipping rate if the package value is over the From value and no To value has been defined.
The RatesAndServicesSelection operation selects shipping rates from the bottom up. More specific shipping rate definitions are selected before global shipping rates.
Geographical exclusions are possible too. Create a shipping rate with an empty rate (=charge amount) and the location of the shipping rate will be excluded from more global shipping rates for the same service.
E.g. To define a shipping rate of $30.50 for all 'International Air' shipments out side the US one would create shipping rate of $30.50 for the world for orders over $0 with a second shipping rate for the US for orders over $0 with a rate of no value.
Please be aware that the query executed by RatesAndServicesSelection is an expensive query to perform and most likey doesn't scale well to thousands of shipping rate entries.
