During the merchant signup process, when you choose Yahoo as your store location, simply input your full Yahoo store URL (e.g. http://www.example.com or http://example.store.yahoo.com) and complete the registration process.
We’ll automatically locate your Yahoo product XML file and import all of your Yahoo Store products to Sell.com.
After the initial import is completed (usually within 24 hours), we’ll check your Yahoo product XML file nightly for product changes, additions, and deletions to make sure we are always displaying your current product lineup and pricing.
Be sure your Yahoo Store is publishing a feed where we can download your listing. Click here to view the Yahoo Store help topic for more information.
