Ok, so from what I have been reading, the dimensions that are entered on the listing should be for the actual item plus whatever material is used to wrap it for protection. Not the dimensions of the box it is shipped in.
But, if I want to use the exact box dimensions in the listing that the item is shipping in, and there is a preference set up for that box size, will the shipping be based on that box size, or will the calculation be made on a larger box size (since the dimensions are exact, will the system look for a larger box)?
If that is the case, I would need to change my dimensions on the listing to adjust, so the right box size is chosen.
