The phrase refers to a promotional alphanumeric string used within a specific mobile application operating in the Kingdom of Saudi Arabia. This application, named “Ninja,” likely provides delivery or e-commerce services. The alphanumeric string, when entered at checkout, typically reduces the overall purchase price.
Such promotional tools serve as incentives for new user acquisition and customer retention. Historically, retailers and service providers have employed similar techniques to stimulate demand and gain a competitive advantage within their respective markets. These offer codes can be time-sensitive, product-specific, or require meeting a minimum purchase amount.
