You're required to specify at least one postage service and cost when listing items.
For most items, you can specify a single, flat postage cost that can reasonably cover the locations you post to.
If you're selling large or heavy items, multiple items, or an item bundle, you can have postage costs calculated automatically based on the package information you provide, the service you select and the buyer's location.
If you are posting items that weigh more than 25kg, select the freight postage option.
