UPS Shipping Rates Add-on Module for Existing Carts

This module queries the UPS server and returns a shipping price based on the parameters you have provided. This is done using a pop-up window so it can be added to any page. The user selects a preferred shipping method, and a pop-up window displays the shipping price. When the user accepts the quote, it is returned to a "read only" field on the checkout page, and the user continues with the checkout process. I spent countless hours searching Perl Script sites for a UPS Shipping module that could be added to a cart that was already in use by one of my customers. What a frustrating waste of time! When I got this script working, I knew I had developed something of great value.
