We are using UPS for our shipping.
Problem: the shipping is not matching UPS amounts for weight (tested our cart against UPS.com).
example: based on ground shipping
Item 1 weighs 8# going from 60610 to 90210
cart shipping = $9.37 (set for UPS shipping)
actual UPS shipping = $10.87
Qty 2 of Item 1 = 16# 60610 to 90210
cart shipping = $13.84 (set for UPS shipping)
actual UPS shipping = $17.41
Where do I differentiate packaging in one box for one item and 2 boxes for 2 items, etc?
Thank you for any help you can give on this issue.
