"Occasional customer frustrations and mistakes are inevitable — especially for a program as popular as Amazon Prime," Amazon said in a trial brief filed last week. "Evidence that a small percentage of customers misunderstood Prime enrollment or cancellation does not prove that Amazon violated the law." But the FTC said Amazon deliberately made it difficult for customers to purchase an item without also subscribing to Prime. "Amazon has long known that millions of its customers struggled with enrollment and cancellation of its subscription service, Prime," the FTC said in its trial brief. Earlier this year, Amazon’s Prime Video service began streaming "The Apprentice," the long-running TV show that boosted Trump’s profile before he ran for president.
