The shipping price for the item.
Additional Shipping Price
The shipping price for each additional item.
For example, if the shipping price is $5 and the additional shipping price is $3 and a customer gets three of the same item, then the customer would be charged $13 for shipping.
If this field is left blank, the customer will just be charged the Shipping Price once. So, continuing the example above, if a customer gets three of the same item, then the customer would be charged just $5 for shipping.
