Do I need to return an extra item when a company makes a mistake in my favor?

[Thomas]

I ordered a case online and about a week later I received two packages, one being mine, and the other not. My mom reported to the company about the mix-up, but they did not send a return label.I want to keep the extra case because I can put it to use, but my mom disagrees with me and says that I need to return it. So, do I have/need to return it? Thanks

You do not need to return it at your cost. If the company makes arrangements for pick-up/shipment, then return it. If not, legally it is yours.

Well the right thing to do would be to return it. Call the company and tell them what happened. If they send you a return label send it back but if they dont then you dont have to spend your own money. I know exactly how you feel and I would probably want to keep it to but again the right thing to do is to give it back. Good luck and maybe they will tell you to keep it.

If you're a completely honest person, you'll ship it back.
However, online companies cater for delays and mistakes and that's incorporated in the price you pay for the product.
Unless your contract specifically says you HAVE TO return it, you don't legally need to.

Your mother has a lot of empathy, she can put herself in the supplier's shoes. If you would be the supplier, would you want to have it returned?
Whether you do or don't, you won't go to jail for it or pay a fine but it's you who has to live with your actions.
