What is the difference between "Best Sellers" and other products?

A “Best Sellers” section is a product-discovery aid that highlights items selected or ranked according to the site’s current merchandising or sales criteria. It is not a guarantee that an item will sell well in every store or market. Check the product page for specifications, MOQ, pack size, price, warehouse, and availability, then compare the item with your customers’ needs. If the ranking criteria are not publicly defined, do not assume the placement represents a specific sales period or volume.
