Does anyone have any idea how much smaller (like exactly.... .25"? .5"?) products need to be than the available box sizes in carrier calculated shipping (Advanced Commerce)?
I have a client who ships some items in their own packaging... so the product size is technically the same as the custom box size that I input in the Shipping tab. We've discovered that we're having issues getting the system to recognize that a 10x10x2 product can fit in a 10x10x2 box... let alone combining 2 or more smaller products with dimensions adding up to any of the 10x10x2... but I can't just run trial and err
