Amazon was tricked by a fake law firm into removing a hot product, costing this seller $200,000

Shortly before Amazon Prime Day in July, the owner of the Brushes4Less store on Amazon's marketplace received a suspension notice for his best-selling product, a toothbrush head replacement.

"Just five minutes of detective work would have found this website is a fraud, but Amazon doesn't seem to want to do any of that," the owner said. "This is like the Wild Wild West of intellectual property complaints."

He said the issue with Amazon was finally resolved on Tuesday after two months of waiting. Losing his best-selling item — a particular type of toothbrush replacement head — resulted in at least $200,000 in lost sales, he estimates.
