Coupon code sites can vary in terms of safety and reliability. Some sites may provide legitimate, up-to-date coupons from reputable sources, while others may host expired or fraudulent codes. It's important to be cautious when using coupon code sites and to stick to well-known and trusted platforms.

Promotional codes are alphanumeric strings that online stores offer to encourage purchases on their website and are typically associated with an overarching promotional marketing strategy. The discount associated with a promo code can apply to individual products or an entire order.
