Online coupons work by providing customers with discounts or special offers when purchasing online. Here's a breakdown of how they typically function:

Issuance: Retailers or brands distribute  online coupons  through various channels, including their websites, email newsletters, social media platforms, affiliate websites, or couponing websites.

Redemption: Customers obtain the coupon code or link and apply it during the checkout process on the retailer's website. The coupon's exact method varies depending on the platform or website, but there is usually a designated field or option to enter the coupon code.

Discount Application: Once the customer enters the coupon code or clicks on the provided link, the discount associated with the coupon is applied to the total purchase price. This discount may be in the form of a percentage off the total, a specific monetary amount off, free shipping, or other promotional offers.

Validation: The retailer's website verifies the coupon code's validity, checking factors such as expiration date, usage limits, and eligibility criteria. If the coupon meets all requirements, the discount is applied to the order.

Completion of Purchase: After the coupon is successfully applied, the customer completes the checkout process and purchases the item at the discounted price.

Post-Purchase: In some cases, customers may receive confirmation emails or notifications that reflect the discounted price and provide details of the coupon used for reference.

Customers need to read the coupon's terms and conditions carefully, as they may include restrictions or limitations, such as minimum purchase requirements, exclusions on certain products or brands, and expiration dates. By understanding how online coupons work and following the provided guidelines, customers can take advantage of discounts and save money on their online purchases.
