The Unsolicited Goods and Services Act 1971 makes it an offence for a company to send you goods you have not ordered. The legislation is intended to discourage companies from sending customers unordered goods in the hope that they will be induced by lethargy or ignorance to pay for them. Companies who send out unordered goods in this way do so at great risk since once you receive the goods you do not have to pay for them and they are yours to keep.
