美国站跟加拿大站的FBA 可以共用吗？ 还是需要另外再寄FBA到加拿大？
我发现Build International Listings，暂时是不支持已经做FBA 的listing的。
With Build International Listings, you can create and update your self-fulfilled listings across multiple Amazon North American marketplaces. We do not currently support Fulfillment by Amazon (FBA) inventory. You enter or update your listings once and then let the tool do the rest. To add your listings to each marketplace, choose your source marketplace and then add a new connection individually for each target marketplace. Please note: Build International Listings will create a synchronized listing in your target marketplace for each of the listings in your source marketplace if an Amazon product detail page exists in the target marketplace. If no detail page exists in the target marketplace for a particular listing, an offer won’t be created for that listing. Learn more about Build International Listings.
