lower shipping rates can be achieved by selecting the most cost-effective shipping methods, comparing carriers, and taking advantage of bulk shipping discounts. For instance, USPS offers discounted rates for businesses that ship frequently, while FedEx and UPS may provide savings on large-volume shipments. Some e-commerce platforms, like Shopify and eBay, offer integrated shipping solutions that help sellers find the lowest shipping rates based on package size, weight, and destination. Using flat-rate shipping boxes, when applicable, can also lower shipping costs significantly for specific shipping options.
