Ron, most people don't care about who delivers their stuff. Companies tend to negotiate shipping costs with the various shipping companies and go with the lowest bidder. This, of course, only applies to companies that ship high volume. The shipping and handling charge usually being fixed the less they actually pay out for shipping the more goes into their pocket. When that site was put up they probably did ship USPS but have since gotten a better rate from DHL. If a few customers aren't happy with that they really don't much care.
