Enlarge / What're ya buyin'? (credit: Aurich Lawson | Capcom) Online retailers that host third-party sellers, like Amazon and Walmart, have extensive, competitively priced electronics selections. But for years, they have also served as playgrounds for fraudulent sellers, who list products with inflated or deceptive performance claims. Worse, some of these products pose a physical threat to customers. The problem has become so widespread that by the end of this month, the federal government will require online retailers to do a much better job of vetting seller credentials, courtesy of the Integrity, Notification, and Fairness in Online Retail Marketplaces for Consumers (INFORM Consumers) Act.
