A Location Group is a resource which is attached to the Postage resource of a Listing. A Location Group represents a group of one or more countries. By default, all Sellers have two Location Groups set: "Domestic" which represents the Seller's home country, and "Everywhere Else" which represents all other countries (ie: International Shipping). However, please note that Sellers can customize their Location Groups, as well as remove the default Location Groups.
Note: Sellers can customize their Location Groups from the Members Area > Selling > Seller Tools > Postage Setup page.
