Does anyone know why sometimes they ship DHL and sometimes they ship UPS? The reason i ask is because UPS will not leave a package at my door, but another other freight company will. I would like to know ahead of time so I can call UPS and tell them to just leave it at my freakin door or deliver it to my work. I get into arguments with the UPS store here, they're a bunch of jerks. Don't wanna help anyone out. So anyways, if you have any clue please inform me.

thanks.
