Just staying, our literally written policy was "Offer DDD": donate, destroy, or "dispose of" (a polite euphemism for "You keep it") the misshipped item. I would have added the Christmas flourish if I were saying it in December, too, but the options would have been the same in July. (n.b. The business does not care what you do. We want to convey, in the politest possible way, that we both don't want it and don't want to talk to you about it.)
