We have an issue where we have an item that is originally 3 pounds but goes inside an 8-pound box due to sizing. This is fine as we will then set the product to around 8 pounds and be done with it. However, when, say 5 of the same item is ordered on an order, we end up using a different box which essentially changes the weights again to be back to around 3 pounds per item instead of 8 pounds per item when purchased separately.
Order 1: 1 of Item X purchased, product weight comes as 8 pounds. Order 2: 5 of Item X purchased, product weight should be 3 pounds each, totaling 15 pounds, not 40 pounds.
Is there any way to attack this type of issue in Magento?
