Yes. Apple Pay, American Express, Visa and Mastercard are accepted, as are cash on delivery and instalments. In Saudi Arabia, cash on delivery carries a SAR 20 charge, which is not returned to you if you send the order back.
With Tamara, you pay in 3 interest-free instalments: the first at checkout, the others over the following two months. You see the schedule on the final checkout step, and a copy is emailed to you. Tabby is also available for “buy now, pay later”, with its details shown at checkout.
