You mean the user has to enter in rate tables for each carrier at the
resolution of weight, destination, and origin. (and possibly number of
items).

I suspect the user would prefer to call the carrier and ask them to quote a
rate, then select the lowest or if they have that information, just run
their finger down the paper table and figure out which is cheapest.
Usually the selling point of this type of thing is that it includes the
tabular data.

I'm trying to develop a shipping calculator to compare courier rates. User
enters rates, and excel sheet calculates comparisons based on user defined
weight, # of items, destination and origin.
