ऐसा करना अवैध है और यह बात का फायदा उठज़ता है कि निजी व्यापारी से सामान ख़रीदने पर आपके अपेक्षया कम अधिकार होते हैं।
If the goods you buy are faulty and you suspect the seller was not trading privately - for example, you see lots of small advertisements with the same telephone number or the seller insists on meeting you at your home - contact your local trading standards department which should be able to tell you if the person is a trader and not a private seller.
