Depending on your volume you can negotiate a lower rate. Check out what the Ebay shipping discounts are for folks selling on Ebay and using UPS. This will give you an idea of where to start. For packages under 2 lbs we find that UPS/FedEx rarely beat USPS Priority even with our discount which is much greater than the published Ebay rates. Don't forget it costs almost as much to ship 25 lbs vs 2 lbs and the USPS is losing money.
