Hi all -
I've been struggling with calculating shipping costs for a online store. I'm using the UPS xml shipping calculator to dertimine shipping costs based on package size and weight, and it works great if I only have one item in the shopping cart!
My problem is determining the overall size of a package when multiple items exist in the shopping cart. I have come up with serveral ways to calculate size, but none of them are very accurate. Does anyone have any info or reference regarding this problem?
Thanks,
Jon
