Surely the dimensions of the 'return' doesn't matter, does it? It's only the weight that matters?

Also, you've got to remember that most of the people doing the returns have no advanced knowledge of the items being returned. They're just employed to process returns and they've got a certain amount they'll be required to do each day, so they won't want to be putting too much of their time into going in to fine detail on every parcel or knowing if it ships in a clear bag or a box or with barbed wire, etc.
