Big Billion Days vs Great Indian Festival: Which Sale Is Actually Better? (Data Analysis)
DataWeave tracked 30,000+ products across both October sales. Flipkart discounted 54% of products. Amazon discounted 26% — and raised prices on 16%. The difference by category might surprise you.
Every October, Indian e-commerce does something unusual: two massive sales run simultaneously. Flipkart's Big Billion Days and Amazon's Great Indian Festival overlap for 5-7 days. Both claim the biggest discounts. Only one is actually better — and it depends on what you are buying.
Here is a data-backed comparison, not platform PR.
The Data Source
DataWeave, a retail analytics firm, tracked over 30,000 SKUs across both sales in October 2023. Their analysis covered Apparel, Home & Furniture, Electronics, and Health & Beauty. This is one of the most detailed independent comparisons available.
What they found challenges the assumption that "both sales are roughly equal."
Overall: Flipkart Discounted Far More Products
The headline finding: during their concurrent sale periods, Flipkart discounted 54% of tracked products. Amazon discounted only 26%.
Even more telling: Amazon left prices unchanged on 56% of products, and actually raised prices on 16% of products during the Great Indian Festival period. Flipkart raised prices on only 6% of its products.
This does not mean Amazon GIF is a bad sale. It means GIF is more selective — Amazon focuses discounts on fewer, higher-value products rather than discounting broadly. Whether that works for you depends on whether your specific product is in the 26% Amazon discounts or the 74% it does not.
Electronics: Both Are Competitive, But Different by Brand
Both platforms offered roughly 50% average discounts on electronics. But the brand distribution was completely different:
Flipkart led on: Smartwatches, earbuds, drones. Also Acer, Philips, Samsung, Lenovo, Bajaj, ASUS — these brands received "almost double" the discounting on Flipkart vs Amazon.
Amazon led on: TVs (44.9% Amazon vs 40.6% Flipkart). Noise earbuds (72.5% Amazon vs 52.8% Flipkart). Lenovo laptops (45.4% Amazon vs 24.7% Flipkart).
The practical implication: check both platforms for your specific brand during the sale overlap. A Lenovo laptop is significantly cheaper on Amazon during GIF. A Samsung earbud is cheaper on Flipkart during BBD. The brand matters more than the platform.
Laptops: Independence Day 2025 Price Comparison
For a more recent cross-platform check, Actowiz Solutions mapped prices of popular laptops during India's Independence Day 2025 sale:
HP 15s Ryzen 5: ₹41,990 (Flipkart) vs ₹43,499 (Amazon) — Flipkart ₹1,509 cheaper.
ASUS Vivobook 14: ₹37,490 (Amazon) vs ₹37,990 (Flipkart) — Amazon ₹500 cheaper.
Same sale event. Price differences up to ₹3,000 on the same product. Checking both platforms is not optional if you want the best price.
Apparel: Flipkart Wins Clearly
Fashion is not close. DataWeave found Flipkart averaged 50.6% discounts in apparel during BBD — the highest of any category on either platform. Amazon's apparel discounts were lower across subcategories.
Exception: women's kurtis and some international brands performed better on Amazon. But for general men's casual wear, athleisure, and mid-range fashion labels, BBD is the better sale.
Smartphones: BBD Has the Exclusive Launches
Flipkart has historically secured exclusive Indian launch rights for several phone brands — particularly OnePlus, Redmi, POCO, and certain Samsung models. These phones only sell on Flipkart during BBD, not on Amazon.
Amazon GIF gets its own exclusives — iQOO, certain Nothing Phone variants, and Motorola edge series have been GIF exclusives in past cycles.
Before planning your phone purchase, check which platform has the model you want as an exclusive. That is a constraint that overrides all price comparison.
Which Sale Is Better? By Category
Electronics (general): Check both. Brand determines the better platform.
Laptops: Flipkart edges Amazon on HP and Lenovo. Amazon edges on ASUS. Compare specific model prices.
Smartphones: Depends on exclusivity. Check which platform has your model first.
Apparel and fashion: Flipkart BBD, clearly.
TVs: Amazon GIF (44.9% vs 40.6% average discounts in DataWeave's data).
Beauty and health: Flipkart led with 39.4% vs Amazon's 33% average.
How to Compare Prices During the Sale Overlap
During the 5-7 days when both sales run simultaneously, use this workflow:
For each product, paste the URL into DetectaDeal to check price history. Is the current "sale price" actually lower than the 90-day average?
Compare the same product URL on both platforms. Prices differ product-by-product.
Factor in bank offers: HDFC runs with Amazon, Axis/ICICI with Flipkart. If you only hold one card, your effective price changes.
Check delivery times: if one platform ships in 2 days and the other in 5, factor that in for time-sensitive purchases.
Pre-Sale Price Manipulation: Both Platforms Do It
DataWeave's data showed Amazon raised prices on 16% of products during GIF and Flipkart on 6%. The inflation typically happens 2-3 weeks before the sale, making the "sale discount" appear larger than it actually is.
The defence: price history. A product at ₹45,000 with a "30% off" sticker during GIF might have been ₹42,000 three months ago. The real discount against the unmanipulated baseline is closer to 7%.
DetectaDeal's price history charts show you the 90-day and all-time price trajectory. Any product with a suspicious price spike 3-4 weeks before a sale event is worth flagging before you buy.
