Amazon is a global marketplace, where sellers can offer products in over 20 categories.
Amazon uses a catalog-driven approach, with just one listing for each product. Sellers simply connect to existing listings then add their price and quantity available.
Sellers can choose whether to fulfill orders themselves or use Fulfillment By Amazon (FBA). This is where a seller ships stock to Amazon's Fulfillment Centers and they fulfill orders on the seller's behalf.
