Grocery delivery firm Instacart has agreed to pay massive refunds after federal regulators exposed billing practices that have been draining customers' wallets for years. Instacart will hand over $60 million in customer refunds following a Federal Trade Commission settlement, marking one of the largest consumer protection payouts in the delivery industry's history. The San Francisco-based company allegedly misled millions of customers about "free delivery" while secretly charging mandatory service fees that can inflate orders by up to 15%, the FTC revealed.
