You can decide if you want to provide your customers with a shipping discount for ordering multiple items from your shop by combining shipping fees. Instructions for combining shipping fees are as follows:
Go to the Int'l shipping page, and then fill out the “2nd item” shipping fee for an already created shipping option.
Customers will be more willing to purchase additional items when the shipping fees for the second item are less than for the first item.
It is not advisable to set the shipping fees for the second item higher than for the first item. If the average shipping fees for purchasing two items is higher than for purchasing a single item, customers will be discouraged from purchasing additional items. Furthermore, this may cause customers to use separate orders to purchase individual items.
