In case consumers purchase commodities on the Internet, on television, over telephone, or by mail order, among others, they shall have the right to return the commodities within seven days of receipt of them without cause. However, the return without cause shall not apply to custom-made commodities, fresh, live or perishable commodities, newspapers or periodicals delivered, audio-visual recordings, computer software, and other digital commodities downloaded online or unpacked by consumers, and also commodities unsuitable for return by nature as confirmed by consumers at the time of purchase. The commodities returned by consumers shall remain intact. Merchants shall, within seven days of receipt of the returned commodities, refund the payments made by consumers for the commodities. The freight for the return of commodities shall be assumed by consumers, except as otherwise agreed upon by business operators and consumers.
