Cash on delivery (COD) is a financial fee that enables the delivery of goods to the addressee without payment in advance. For the possibility of payment at the moment of delivery, the recipient pays a small financial sum to the carrier or transport company, then pays the parcel value upon delivery/pick-up. The amount paid is then transferred to the online shop = the sender. Cash on delivery, however old-fashioned, is a form of protection for the buyer, who in this way reduces the risk of possible fraud.
