Cash on delivery

Cash on delivery (COD), sometimes called payment on delivery, cash on demand, payment on demand or collect on delivery is the sale of goods by mail order where payment is made on delivery rather than in advance. If the goods are not paid for, they are returned to the retailer. Originally, the term applied only to payment by cash but as other forms of payment have become more common, the word "cash" has sometimes been replaced with the word "collect" to include transactions by checks, money orders, credit cards or debit cards.
