Every October, Flipkart's Big Billion Days and Amazon's Great Indian Festival go head-to-head in the biggest shopping event of the year in India. For five to six days, both platforms run thousands of deals across every product category. Live tracking is on the Amazon India price tracker and the Flipkart price tracker.
If you approach it correctly, these events genuinely are the best time to buy certain products. If you approach it without preparation, it is easy to spend a lot of money on deals that were never actually deals.
This guide is about the former.
Before the Sale: Do Your Research
The best deals go early — often in the first few hours of the sale. To take advantage, you need to know what you want before the sale starts.
Step 1: Make your list. Decide in advance which products you want to buy. Do not wait until the sale is running to browse. Sale-browsing under time pressure is when bad decisions happen.
Step 2: Check current prices. For each product on your list, note the current price on Amazon and Flipkart.
Step 3: Check price history. Paste each product link into PriceDiff and look at the chart. This tells you: - What the lowest price for this product has ever been - Whether the product has dropped significantly during previous October sales - What a genuinely good price for this product would look like
Products that showed genuine deep discounts in previous October sales are worth prioritising in the upcoming one. The Lowest Price Ever page shows what's currently at a historical low across all four marketplaces.
The 'Pre-Sale Price Spike' Warning Sign
Watch for this pattern: in the two to three weeks before Big Billion Days or Great Indian Festival, some products show a price increase on PriceDiff's price history chart. The price then "drops" to roughly where it was before the spike at the start of the sale.
This is the MRP inflation pattern in action, described in more detail in our guide to fake discounts and our explainer on MRP. If you see this pattern on a product you want, the "sale price" is not a genuine discount — it is a return to the regular price with a discount label on it.
During the Sale: Move Fast on Genuine Deals
With your research done, the sale itself becomes much simpler. For each product on your list:
1. Check the sale price against the all-time lowest you noted from PriceDiff. 2. If the sale price is at or below the all-time low — buy immediately. Genuine deals at all-time lows sell out or expire. 3. If the sale price is not below the historical price range — skip it or wait. It may drop further, or it may not genuinely be a deal.
Do not be pressured by countdown timers or "X people viewing this" labels. These are psychological pressure tools. The price history chart is objective data; the sale countdown is marketing.
Categories Worth Targeting
Based on price history patterns, these categories consistently show genuine deals during October sales:
Smartphones (mid-range, ₹10,000–₹30,000): Consistent genuine drops, especially on Xiaomi, Realme, Samsung M-series, and previous-generation flagships. Often the all-time low for many models.
Large televisions (43-inch and above): TV brands actively participate in these events with real discounts to drive brand visibility. A 55-inch 4K TV from Samsung, LG, or Sony will often hit its annual lowest price.
Kitchen appliances: Mixer-grinders, air fryers, OTG ovens, and food processors often see genuine deals. Check history — established brands with consistent price histories are safer bets.
Earphones and TWS earbuds (established brands): Sony, Jabra, and JBL models show real discounts on these platforms. Be more cautious with unknown brands.
Categories to Approach With Caution
Fashion and apparel: High MRP inflation. "80% off" is common. Check price history every time — do not rely on the discount percentage.
Small electronics accessories: Cables, power banks, chargers. The market is flooded with low-quality products with inflated MRPs. Stick to reputable brands and check price history.
Furniture: MRP inflation is rampant. Prices are inconsistent. Hard to compare across sellers.
Bedsheets, curtains, home textiles: Same issues as fashion. MRP is essentially arbitrary in this category.
After the Sale: Wait-and-See Sometimes Works
Not every deal happens on Day 1. Both platforms often deepen certain discounts mid-sale if initial sellthrough is below expectations. The best strategy:
- Buy on Day 1 if the price matches or beats the historical low.
- If a product is not yet at the historical low on Day 1, check again on Day 3 and the final day.
- Some products hit their all-time lows only in the last 24 hours as the event ends.
PriceDiff's price history updates as prices change, so checking the page on each day of the sale gives you a running picture.
The Bottom Line
Big Billion Days and Great Indian Festival are genuinely the best times to buy certain products in India. The key to using them well is separating genuine deals from manufactured ones — and the price history chart is the only tool that does that reliably.
Before the sale: check price history for your target products. During the sale: compare the sale price to the historical low. That two-step process turns the world's most discount-label-heavy shopping event into a genuinely useful savings opportunity.
