I am having customers contacting me that their packages have not been delivered even though the UPS tracking says Delivered. Now I realize it is due to UPS Ground Saver purchased through Amazon Shipping that indicates "Delivered" at the local post office not at the residence of the customer! Hopefully they will then deliver to the residence of my customers but in the meantime I have to continue contacting them to find out and worry that I will get dinged for "too many customer contacts" and non delivery problems.
