Ok, I am shipping enough items now that I got UPS's attention and I am in the middle of negotiating better rates with them based on my shipping volume. My question is, how can I get ZenCart to retrieve these rates and display them to the customer when using the checkout. I think that the UPS module just retrieves the standard rates based on the shipper and customers zip codes and package weight. I looked but I could not find any information regarding this on the forum or in the downloads section.

Thanks,
Marc
