If you're based in the US or Canada, you may have USPS or Canada Post shipping rates automatically calculated for your orders by using calculated shipping. With calculated shipping, costs are determined based on the total weight and dimensions of an order, the buyer's address, and the shipping service that the buyer selects during Checkout.
Each seller determines their own shipping rates.
You can only enter one "One item" and "Each additional item" rate for each country.
We understand that rates can vary due to weight and distance. If you're concerned about this, we recommend you charge a high estimate while explaining in your listing descriptions that you'll refund any extra postage. You can then refund the buyer via the method they paid. You may also want to figure an average, so you may lose money on some shipments but gain it back on others.
You're also welcome to note that shipping prices vary in your listing descriptions. Ask buyers to contact you prior to purchasing for a more exact shipping quote. Then you can edit the listing's shipping rate and reserve the listing for your buyer. Learn how to reserve a listing.

How do I add shipping rates to my listings?
When listing a new item, in the Shipping area, use the dropdown menu next to Shipping origin to choose the country where your item will be shipping from.
Next to Fixed shipping costs, click Add another location. Once you choose the countries you'd like to ship to, fill in the shipping costs per destination. To remove a country, click the trashcan icon to the right of the country name.
Everywhere Else means everywhere in the world aside from your other shipping rates. If you don't want to ship everywhere, you can still choose the countries you will ship to and can remove Everywhere Else from your shipping list.
