No, you paid for a really nice box that you can use yourself for storage purposes, or to ship your own item/s to someone else.

Why would you even do that if you can't remember ordering something?

Once I accepted the package and Opened it, I saw that it was from CVS. The order I had placed was not delivered, however, I was charged for missing items.

you don't have to pay to pick up a package from the post office.

if you actually read the post he went to UPS not USPS

Depends on the country. Also, dude went to a UPS store, which is not the Post Office.

It wasn’t the post office if had bothered to read. It was UPS. The package was not marked on the outside. However after opening it, I saw that I had placed an order with CVS. There was nothing in the package. I was charged for nothing.

OP - Empty packages could be part of an elaborate scam for a seller artificially to inflate their sales and ranking. They are scamming the selling site, not necessarily the recipient.

Google “receiving empty packages from china”

You paid for the “experience.”

People are often happier paying for experiences than for tangible objects. Not sure I’d want the “trip to the UPS Store” experience, but you do you.

You have to pay to pick a package up?

in services like UPS, DHL, FedEx etc it is possible to send packages and have the receiver pay for them instead of the sender

The amusing thing is that most freight companies will default back to the sender for payment if the package is not delivered/collected. So if you aren't expecting a receiver pays package and there's no identifying information on the consignment as to who sent it with a customer reference.. just don't accept delivery. They can't force you to accept it.

Wouldn’t you check the return label?

Were you expecting a package that you had previously paid for items?
