My experiences with UPS have been bad every time. Once I ordered flowers that the vendor shipped via UPS and UPS held the flowers in their warehouse for a week!
Another time, I purchased an item to be delivered to my office. For some reason the Suite number was not added to the shipping label. The vendor called back requesting UPS add the suite number within the window of time accepted. Rather than accepting the change they have refused to deliver the package.
Now I have to drive 20 minutes out of the way to get the package from the UPS shipping facility.
The vendor was apologetic and said that they did everything correctly, but someone at UPS did not make the changes per their own policy! I am at the point where I have considered not shopping from vendors that use UPS!
