If you’ve ever shopped online, you’ve probably seen a box that says “Apply Coupon Code” or “Enter Promo Code.” But what exactly is a coupon code? And how does it help you save money?

In this simple, beginner-friendly guide, I’ll break down everything you need to know about coupon codes — how they work, different types, where to find them, and why brands use them.

So, What Is a Coupon Code?

A coupon code (also known as a promo code, discount code, or voucher code) is a special combination of letters, numbers, or words that gives you a discount when you shop online. You enter this code during checkout, and the website automatically reduces the price.

Example:

  • SAVE10 = 10% off
  • FREESHIP = Free shipping
  • WELCOME50 = ₹50 or $50 off on first purchase

Think of it as a digital version of the old paper coupons, but much easier to use.

  1. Add products to your cart.
  2. Go to checkout.
  3. Find the “Apply Coupon” or “Promo Code” box.

  5. Click Apply and watch your price drop instantly.

The discount can apply to:

  • Total bill
