When multiple sellers are selling the same product, the customer can view a list of offers.
Use a standard product identifier when submitting your products. The three top standards are ISBN, UPC, and EAN. This is the most important and reliable piece of data in the matching process.
The manufacturer part number is different from the SKU. The manufacturer part number is the standard by which manufacturers identify their products.
If you are creating child products for a variation, each child item must have the correct and unique UPC or manufacturer part number.
This data is almost always required to create a new product.
For example, product dimensions such as height, width, and weight should be specified in the Height, Width, and Weight attributes. Do not use general purpose merchandising fields for these values.
Do not include merchandising information in the item name. Use the product description and the bulleted list for adding merchandising details. For example, do not include "Reduced Price" in the name of the article.
If you must change your SKU for a product, do not re-use or recycle old SKUs. Issue a new SKU for the item, and then re-assign the product to the new SKU.
If you create parent and child products for variations, the product data for the parent product should contain only data that is common to all child products. This includes Item Name, Product Description, Featured Bullets, and so on. Standard identifiers such as UPC, EAN and manufacturer part number are unique for each child product. Do not copy these values into the attributes for the parent product.
