Add New Box
To add a new Box,you will need to enter a name of your Box as well as its dimensions. Please note that the dimensions are the outer dimensions of your Box which will be used to calculate the quotation of your shipment.
With each Box, you can decide if it should be available for auto selection or not.
This means that Easyship will only use your available Box when calculating rates.
For example, if you only ship one type of item you may opt for having one box for 1 item, one box for 2 items and one box for 4 items.
This would mean that if you save all of these boxes and someone places an order for 3 items, Easyship would automatically choose the box size for 4 items.
You can edit your saved Boxes by clicking them.
Please note that you are not able to change the dimensions of a saved box.
