Flipkart Big Billion Days: are the discounts real?
We checked what actually happened to 183 tracked products through the last two Big Billion Days — not what everyone says happens.
What we found
Pre-sale markups are real, and worth watching for. They are also a minority: across 183 tracked Flipkart products with complete price records through the 2024 and 2025 sales, roughly one in five got more expensive in the weeks beforehand. For most of the rest, the sale price was genuinely the better price.
- beat their pre-sale price
- 83%beat their pre-sale priceThe lowest price during the sale came in below what the product had been selling for beforehand.
- were marked up first
- 19%were marked up firstTheir price in the run-up sat more than 2% above the month before it — the pattern worth checking a chart for.
- beat it by more than 10%
- 63%beat it by more than 10%Discounts deep enough that waiting for the sale clearly paid off.
Season by season
| Sale | Products | Marked up | Beat pre-sale price | Low landed on |
|---|---|---|---|---|
| Big Billion Days 2025 | 79 | 13% | 85% | 25 September |
| Big Billion Days 2024 | 104 | 23% | 82% | 29 September |
Among the products that were marked up, the median markup was 8% in 2025 and 9.9% in 2024 — small enough to hide behind a big advertised discount, large enough to matter on an expensive item.
When the discount wasn’t one
These are real products from our own records. Each one climbed before the sale, then carried a discount measured from the higher price. Open any of them to see the full timeline.
- Before
- ₹1,099
- Run-up peak
- ₹1,498
- +36%
- Sale low
- ₹1,099
- +0%
Marked up 36%, then sold at exactly its old price. Nothing was saved.
- Before
- ₹2,249
- Run-up peak

- +23%
- Sale low
- ₹2,699
- +20%
The cheapest it got during the sale was 20% more than before it.
- Before
- ₹3,599
- Run-up peak
- ₹5,039
- +40%
- Sale low
- ₹2,549
- −29%
Both at once: a real 40% markup, and a real 29% saving. The advertised discount was still overstated.
And when it genuinely was
The more common outcome, and the reason it is worth shopping the sale at all. Note the last one: a real saving that had nothing to do with the sale.
- Before
- ₹8,995
- Run-up peak
- ₹8,995
- Sale low
- ₹4,849
- −46%
No run-up at all, then 46% off. This is what a real sale looks like.
- Before
- ₹1,720
- Run-up peak
- ₹1,049
- Sale low
- ₹817
- −53%
Already falling before the sale, and it kept falling. 53% below baseline.
- Before

- Sale low
- ₹599
- −25%
Marked up 25% first — and still ended 25% cheaper than before the run-up.
The method, so you can weigh the numbers
For each product we take the median price across a pre-sale baseline window, the median across the run-up window immediately before the sale, and the lowest price recorded during the sale itself. A product counts as marked up if its run-up median sat more than 2% above its baseline. Only products with recorded prices in all three windows are counted.
What this cannot tell you
We record the selling price a shopper actually pays, not the struck-through MRP shown next to it. A listing whose MRP is inflated while its selling price stays put would not register here — so this audit can neither confirm nor rule out MRP inflation specifically.
We measured that separately, and it is the larger effect of the two: what a discount badge actually means on Flipkart.
Prices are captured from public listings at the time of crawl and are aggregated for analysis; very short flash sales may be missed, and figures are indicative rather than a complete record of every price a listing ever showed. Always confirm the current price on Flipkart before buying.

Flipkart Big Billion Days — FAQs
When is Flipkart Big Billion Days 2026?
Flipkart has not announced the dates yet. In our own price records the deepest prices of the sale landed on 25 September 2025 and 29 September 2024, so the last week of September is the window to plan around. We update this page when the dates are confirmed.
Does Flipkart raise prices before Big Billion Days?
Some listings do, but it is not the norm. Across 183 tracked products through the last two sales, 19% were selling for more than 2% above their previous month's price in the run-up — roughly one in five. The median markup among those was around 8%. The other four in five were flat or already falling. Treat the markup as a real risk on individual products rather than a blanket rule.
Are Big Billion Days discounts genuine?
Usually. For 83% of the products we tracked, the lowest price during the sale genuinely beat what the product had been selling for beforehand, and 63% beat it by more than 10%. The advertised percentage is still often overstated, because stores calculate it from the list price rather than from the recent selling price — but the underlying saving was real more often than not.
Should I wait for Big Billion Days to buy?
On the evidence, waiting pays off more often than not — but not always, and not for everything. We found products that hit their lowest price before the sale opened and never moved again during it. The reliable approach is to start tracking the specific product now, so that when the sale price appears you can compare it against a benchmark you recorded yourself.
How do I check whether a Big Billion Days deal is real?
Open the product's price history page on Price History and look at the last three months. If the line steps up in the weeks before the sale and the "deal" price sits at or above where it was before that step, the discount is measured from an inflated base. If the line is flat or falling and the sale price breaks below it, the saving is real.
Why is the advertised discount bigger than the saving you show?
Stores calculate the advertised percentage against the listed MRP, which is often far above what anything actually sells for. We calculate against the product's own recent selling price, which is the number that decides whether you are better off. We record the selling price a shopper actually pays, not the struck-through MRP shown next to it. A listing whose MRP is inflated while its selling price stays put would not register here — so this audit can neither confirm nor rule out MRP inflation specifically.
