Customers who go to Best Buy's website will be able to find products that weren't available before, as it allows items to be sold by third-party sellers, such as seasonal items, small kitchen appliances, cookware, furniture, and tech-related accessories like custom video game controllers.

Best Buy is just the latest company to adopt the marketplace-as-a-service strategy. Amazon has a third-party marketplace, as does Walmart, Lowe’s, Nordstrom, Kohl’s, Macy’s, and Target. (Just to name a few.)
