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.
For compatibility with parent class
Cache always disabled for Offline lookups: they are so fast already, the disk I/O of a running a cache is not worth it.
$zip Input to shorten/lengthen. Usually a zip code.
Shorten to three digits. If the input doesn't have leading zeros, add them.
