|Postage costs are automatically calculated for the buyer|
When you use calculated postage, buyers looking at your listing can choose to see all the postage services you offer by clicking the See more services link in the Postage section. When they do, a table of postage costs will appear based on the buyer's location. Only the postage services you offer will be shown. For international postage, any handling costs are included in the postage cost.
Tip: If you send an eBay invoice to a buyer or you enter payment details in Selling Manager, the postage charges you enter will override the calculated cost.
