Conflicting shipping rates between AbanteCart & UPS Server

[Ollie]

I am getting different shipping rates between the UPS server and my AbanteCart store. I used the same parameters (same zip codes, same weight, same dimensions, and same type - residential vs commercial) but I'm getting rates that don't match!

Hi. Please provide example of 'parameters' and how do you check "UPS server" without AbanteCart?
