Using a coupon code in India is a simple process. Here are the general steps to follow:

1. Find a coupon code that you would like to use. You can find coupon codes on various websites, including our website, or through email promotions from the retailer.
2. Copy the coupon code. Make sure to copy the code exactly as it appears, as codes are often case-sensitive.
3. Add the items you wish to purchase to your online shopping cart.
4. Proceed to checkout.
5. Find the coupon code field or box. This can typically be found on the payment page or in the order summary section. It’s usually labeled as “Enter promo code,” “Apply coupon,” or something similar.
6. Paste the copied code into the coupon code field.
7. Click the “Apply” or “Submit” button to apply the coupon code to your order.
8. Review the final total to ensure the coupon code has been applied and that the correct discount has been applied.
9. Complete your purchase by entering your payment and shipping information.

Keep in mind that not all online retailers in Singapore accept coupon codes and also some coupon codes are country-specific and can only be used in that country. Always check the coupon code T&C before using it.
