I have my packages delivered to a UPS Store box.
I routinely get notifications that an Amazon driver attempted to deliver while they were closed, when I have the store hours listed in the delivery instructions.
And more than once I’ve been told they didn’t deliver because they were closed, when I know for a fact that they weren’t.
I’m sorry. Things like that have happened to us more often with FedEx, than UPS; and never (so far) with Amazon.
But I live in an apartment building, and I’m almost always here. When I haven’t been, they’ve just left it at the door, per instructions.
