There is no one-size-fits-all answer to this question, as the cheapest way to ship for eBay will vary depending on the specific circumstances of each seller and buyer. However, some tips on how to get the best shipping rates for your eBay transactions include: Use FedEx or UPS for larger items, as they typically offer better rates than the USPS. If you are shipping internationally, consider using a service like eBays Global Shipping Program, which can save you money on cross-border postage. If you are selling multiple items to the same buyer, consider combining them into a single shipment to save on shipping costs.
