I never really knew about "dimensional weight" charges until recently when I was shipping a lightweight item around 3lbs, but the dimensions on the item were large; so I was actually getting billed on a 6lbs "dim weight" instead of the 3lbs "item weight".
These "dim weight" shipments have definitely been taking a toll on calculating an accurate shipping cost based on "dim weight"; since not all my products in my database list the dimensions of the item.
So lately if I catch an order with large dimensions and it isn't saved in my database I will cancel the order and let my customer know that the shipping wasn't calculated properly and most of the time they re-submit the order with no issues.
However, if I miss an order that has large dimensions which isn't saved in my database and my supplier ships the item out to me; I end up performing some origami tactics to get the item to fit in the smallest box possible...haha.
What is your experience with "dim weight"; do you guys usually get charged with "dim weight" more times than "item weight"?
