I spend on average $2000/mo. w/ UPS shipping pressure washers all over the U.S. and have just gotten a very attractive pricing quote from DHL. My question is, does anyone know how they are to deal with? Are they professional, friendly, etc? I think UPS can be a bit of a PITA and they constantly over-charge us each month. Thanks in advance for any help, this is very important to my daily business operations. Jerry.
