Its not stealing. here is a statement from a law place:
If you ever receive an unordered item, you may feel obligated to pay for it or return it. Don't. If you didn't order it, and it isn't being sent as part of a negative option or club plan, you can keep it for free. If you are billed for merchandise you did not order, advise the company that unless it can demonstrate you ordered it, you will treat it as a gift. If you have any questions about unordered merchandise, contact the FTC.
