how to reduce shipping costs on amazon is a frequent concern for FBA sellers and merchant-fulfilled sellers alike. There are several proven strategies to achieve lower shipping costs while maintaining delivery speed and customer satisfaction. First, optimizing packaging dimensions can significantly reduce dimensional weight charges. Second, leveraging Amazon’s Partnered Carrier program can offer discounted rates for inbound shipments to fulfillment centers. Sellers should also consider storing inventory in warehouses closer to high-demand regions to shorten last-mile delivery distances. Batch shipping and using third-party prep centers with bulk rates may further cut expenses. Understanding how to reduce shipping costs on Amazon is essential for improving margins and staying competitive on the marketplace.
