Big Billion Days & Great Indian Festival: how to actually save

India's mega sales — Flipkart's Big Billion Days and Amazon's Great Indian Festival — are the cheapest windows of the year for electronics and appliances. But not every 'deal' is a real deal. Here's how to shop them smartly.

1. Note the real price before the sale

Some products are quietly marked up just before a sale, then 'discounted'. Check the price a week earlier so you know the genuine drop.

2. Compare across both sales

The same item is often cheaper on one platform than the other, and it changes day to day. A quick comparison beats loyalty to one app.

3. Stack a bank offer

• Instant discounts on specific bank cards can beat any coupon.
• Check which card gives the best offer before you pay.

4. Use a wishlist and price alerts

Add what you want in advance and let a price-drop alert tell you the moment it hits your target — no need to refresh all day.

5. Don't rush the add-ons

Extended warranties and accessories bundled at checkout are usually cheaper bought separately later.

The bottom line

Compare the price across stores on KartCompare, layer a bank offer, and buy at your target — that's how you win the sale instead of just feeling like you did.
