选择您的来源商城和目标商城
在连接商品前，您需要选择一个来源商城和一个目标商城。来源商城将成为您管理商品价格的主要位置。当您更改来源商城的商品价格时，已连接商品在目标商城中的价格将自动更新。
选择来源商城
选择来源商城时，请考虑以下因素：
如果您目前仅在一个商城中销售商品，请选择该商城作为您的来源商城。
如果您在多个商城中销售商品，可能需要选择所列商品种类占比最大的一个商城作为来源商城。
注意： 在选择第二个来源商城时，您将在屏幕右侧看到用作参考的第一个来源商城和目标商城。只有您未指定为来源商城或目标商城的商城才可被选为第二个来源商城或目标商城。
选择目标商城
选择目标商城时，请考虑以下因素：
在您当前拥有商品的目标商城中，您可以选择保留或删除现有商品。
——如果您选择保留现有商品，且来源商城和目标商城中同时具有相应的 ASIN，则商品价格将进行同步。
——如果您选择删除现有商品，则所有商品、历史记录和评论均将被删除。如果来源商城和目标商城中同时具有相应的 ASIN，则系统将创建和同步新的商品。您无法撤消此操作。
在建立国际商品信息页面上，选中您要连接的每个目标商城旁边的复选框。如果您想在所有选定商城中应用相同的设置，请选择【将相同设置应用于所有商场】。
注意： 您可以随时编辑目标商城设置。无论您在何时更新商品价格规则，此工具都将重新计算目标商城中的商品价格。更改商品价格后，最新价格可能最多需要 4 个小时才会显示在各个目标商城中。

Choose your source and target marketplaces
Before connecting offers, you need to select a source marketplace and a target marketplace. You will use the source marketplace as the primary place to manage your prices. Target marketplace prices for connected offers will update automatically whenever you change your source marketplace prices.
Choose your source marketplace
Consider the following when choosing your source marketplace:
If you currently sell in only one marketplace, select that as your source marketplace.
If you are selling in multiple marketplaces, you may want to select the one in which you have the most offers as your source marketplace.
Note: When selecting a second source marketplace, you will see your first source and target marketplaces on the right side of the screen for reference. Only marketplaces that you have not already designated as a source or target marketplace will be available to select as a second source or target marketplace.
Choose your target marketplace
Consider the following when choosing target marketplaces:
In target marketplaces where you currently have offers, you can keep or delete the existing offers.
——If you keep existing offers and the ASIN exists in both the source and target marketplaces, the prices will be synchronized.
——If you delete existing offers, all offers, histories, and reviews will be deleted. New offers will be created and synchronized where the ASIN exists in both the source and target marketplaces. You cannot undo this action.
On the Build International Listings page, check the box next to each target marketplace where you want to connect. If you want to apply the same settings to all selected marketplaces, select Apply same settings to all marketplaces.
Note: You can edit your target marketplace settings at any time. The tool will recalculate the prices of your offer in the target marketplaces whenever you update a price rule. It may take up to four hours before the price changes are reflected in each target marketplace.
