COD in a card-and-wallet market
Recent analyses put COD at roughly 18-22% of Saudi e-commerce, with higher shares in electronics (31%) and furniture (28%), against over 70% in 2016. Mada, the national debit network, and digital wallets carry most online payments.
So COD in Saudi Arabia is an option to convert hesitant buyers and higher-ticket orders, not the only way to pay. Offer it, and measure how many of those orders you actually deliver.
