Cash on delivery

Cash on delivery (COD), sometimes called collect on delivery or cash on demand, 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.

Limits.
Most operators impose a limit on the amount of money that can be collected per delivery or per day using COD services. Limits may be higher for non-cash payments. Canada Post, for instance, applies a limit of C$1000 for cash, but C$5,000 for payment by check or money order.
Popularity in the developing world.
In some countries COD remains a popular option with internet-based retailers, since it is far easier to set up for small businesses and does not require the purchaser to have a credit card. Many small businesses prefer cash payment to credit card payment, as it avoids credit card processing fees. Some shops also offer discounts if paid in cash, because they can offer a better price to the consumer.
