Yes, using Tabby or Tamara. At checkout you select the provider and link a card, and the total is spread over 3 or 4 payments free of interest and fees. Any Saudi resident aged over 18 can use it, and your spending limit is set by the products you choose and your history with the provider.
Returning an item reduces the payments you still owe. Where the refund exceeds your outstanding balance, the rest of the payments are cancelled and the difference comes back to you.
