Business::Shipping::RateRequest::Offline - Abstract class for cost calculation.

This doesn't have very much to it. It just disables the cache feature, and has a few miscellaneous functions.

* perform_action()

For compatibility with parent class

* cache()

Cache always disabled for Offline lookups: they are so fast already, the disk I/O of a running a cache is not worth it.

* make_three( $zip )

 $zip   Input to shorten/lengthen.  Usually a zip code.

Shorten to three digits. If the input doesn't have leading zeros, add them.
