lightweight shipping refers to shipping methods designed for small, lightweight items that are easy to transport. For e-commerce businesses, offering lightweight shipping options helps keep costs low while still providing customers with fast and affordable delivery. Lightweight items are often sent using services like First-Class Mail or international airmail, which can offer quicker delivery times and lower prices than heavier, bulkier shipments. By optimizing packaging to reduce weight and choosing the best shipping methods, businesses can save on shipping expenses.
