I placed my order for the The Doobie Brothers Quadio set after reading the enthusiastic reviews on this site. Was pleased it was in stock and received an e-mail on 9/19/2020 saying the order had shipped via UPS 3 Day Select and was provided a tracking number and link to the UPS tracking site. Great! BUT every time I check the tracking site, it says the number I have is not in their system and they have no information on it. Wrote to Rhino and they responded UPS is delayed and to keep checking which I have and it still does not register as a UPS valid tracking number! Anybody else run into anything like this?? I am anxious to get and listen to these discs and it is already 9/27 - - so much for 3 Day Select!
