We're in testing mode to turn on our site. We are allowing international shipping, however the rates I get from Zencart/UPS is much higher than from UPS.com. I realise I have handling charges of just over $2.00 but we're talking $80 to $150.00 dollars over UPS.com published rates. I don't really know where to look to figure this one out. It seems if Zencart/UPS is getting it rates from UPS.com then the rates should be equal or much closer. How should I proceed to test this issue?
