A Quick History of Coupon Codes

The first-ever coupon dates back to 1887, when Coca‑Cola mailed out paper vouchers for free drinks. By 1913, 1 in 9 Americans had enjoyed a free Coke thanks to these coupons—a brilliant marketing move that turned Coke into a household name.

In India, coupon culture started with newspaper clippings and mall vouchers in the late 1990s. But everything changed when e‑commerce boomed. With the rise of Flipkart, Amazon, and Myntra, digital coupon codes became a norm.

Today, we’re in the era of dynamic, AI‑driven coupons. Brands like Meituan in China or Instamart in India now generate personalized coupon codes based on your shopping habits. Some codes even decrease in value the longer you wait—encouraging you to buy immediately.

Coupons have evolved from paper slips to powerful digital tools—and they’re only getting smarter.

Types of Coupon Codes

There’s no one-size-fits-all discount. Here’s a breakdown of the most common coupon code types:

Tip: Stack with cashback offers for double savings.

2. Flat Discount Codes

Example: FLAT500 → ₹500 off on orders above ₹2,500.

Best for: High-value products like smartphones or furniture.

Tip: Check minimum spend—most flat codes have one.

3. Free Shipping Codes

Example: FREESHIP → No delivery charges.

Best for: Small orders (where shipping can be 20–30% of the price).

Tip: Some free-shipping codes apply only to app users.

4. Buy One Get One (BOGO)
