Amazon Great Indian Festival 2026 opened at 12 a.m. on 8 October 2026, the start date Amazon published on its own newsroom, one day before Flipkart's Big Billion Days opened to everyone. The confirmed bank offers on Amazon's event-page banner are a 10 percent instant discount on SBI debit cards, SBI credit cards and SBI credit card EMI (up to Rs. 57,750 off), 5 percent unlimited cashback with the Amazon Pay ICICI Bank credit card, 10 percent cashback on Amazon Pay Later EMIs and up to 10 percent extra savings for Prime members. Amazon has not published an end date. This living page tracks the sale, the bank offers and a 15-minute prep checklist, updated through the festival.

Flipkart Big Billion Days 2026 is official: the sale starts 9 October with early access on 8 October for Plus, Black and Flipkart credit card members, and Axis Bank and ICICI Bank cards get a 10% instant discount. This living page tracks the official announcement, the expected timeline (teaser week, early access, flash windows), Axis/HDFC bank offers, which categories genuinely bottom out at BBD vs what to buy earlier, and how BBD compares with Amazon Great Indian Festival - re-verified every week until the sale goes live.

Flipkart's "wifi router", "wifi range extender" and "dsl modem router" results read on 25 October 2026: 116 listings, 115 of them printing a Mbps figure, 93 rated. Priced against that figure the shelf runs Rs. 0.61 to Rs. 30.17 per stated megabit, median Rs. 3.50. Seventy-six of the 115 state exactly 300 Mbps - and inside that one tier the ticket runs Rs. 849 to Rs. 3,299 and the badge runs 1% to 76%. The deepest discount in the read, 76%, is Rs. 4.05 a megabit on four ratings; one of the cheapest megabits, Rs. 1.67, is badged 43%. No listing here states an MRP above 8x its price, which is unusual and to this shelf's credit. The Mbps figure is a theoretical link rate, not throughput. Nothing was bought or speed-tested.

Reliance Digital publishes the full terms of every card offer it runs as a separate page on its own site — 428 of them are listed in its own sitemap. We read fifteen on 25 October 2026. The "up to" figure is always the top-slab figure. The festive SBI offer headlined "Up to 15000 Instant Discount" pays Rs. 1,500 at its own Rs. 15,000 minimum; Rs. 15,000 needs a Rs. 2,00,000 purchase on credit card EMI. Above Rs. 50,000 the slabs are flat amounts, so the effective percentage falls as you spend more within a slab. Every offer page also excludes No Cost EMI transactions, so the instant discount and No Cost EMI cannot be combined — the product page does not say so. Two offers are live today; four indexed pages have already expired. Nothing was purchased and no card used.

Reliance Digital hosts the full terms of every payment offer it runs on its own site. We read seven UPI and coupon documents on 25 October 2026. The live UPI offer caps at Rs. 2,000; the live card instant discount caps at Rs. 10,000 — and because every page forbids clubbing, the method chosen at the last screen is worth up to Rs. 8,000 on a large basket. Two of these pages also contradict their own headlines: one is headed "5% upto Rs.5000" over a bullet reading "5% upto Rs.1000", another "Flat 5%" over a bullet reading "Flat 10%". Both have expired. The Smart Offer coupon pays Rs. 500 at Rs. 5,000 and Rs. 1,000 at Rs. 10,000, to "select customers" only, till 31 October 2026. A larger WhatsApp coupon was redeemable in-store only and ended 4 October. Nothing was purchased and no UPI transaction made.

Reliance Digital runs No Cost EMI under two separate sets of published terms, both hosted on its own site. We read both on 25 October 2026. The rule that catches people out is the first one: the cart must contain exactly one item. Both pages state that any additional product or service item — installation, a warranty, an accessory — "will automatically disqualify" the No Cost EMI and the brand cashback with it. The TV and large-appliance scheme is stated valid till 30 November 2026; small domestic appliances till 31 December 2026, naming only HDFC, SBI and ICICI. Both warn that your own bank may charge an EMI conversion fee the store does not control. And because No Cost EMI is a brand-subvented transaction, it is excluded by name from every instant bank discount the store runs. Nothing was purchased and no EMI taken.

Amazon's "comforter double bed", "quilt razai double bed" and "duvet insert" results read on 25 October 2026: 86 listings, 80 rated, and only 34 stating a GSM figure. GSM - grams of filling per square metre - is the only published number that says how warm a comforter is, and grouped by it the discount runs backwards: 200-220 GSM averages a 70% badge, 300-400 GSM 56%, and genuine 500-600 GSM winter weights just 44%. Fifteen of the 34 are exactly 220 GSM and most call themselves an "AC Comforter" - summer bedding - in their own titles. The cheapest listing is Rs. 399 at 120 GSM badged 80%; the best-reviewed 500 GSM is Rs. 3,200 badged 29%. Four round MRPs cover 45 of the 86 listings. Nothing was bought or slept under.

The same three kitchen queries read on two retailers on 25 October 2026: 190 Flipkart listings and 79 Tata CLiQ listings for knife sets, chopping boards and dish racks. Each leaves you unable to judge what you are buying, by opposite routes. Flipkart's median discount badge is 74% on a median stated MRP of 3.87x the price — with Rs. 999 printed as the list price on 57 listings, 30% of the shelf, and 59 listings claiming more than 5x. But 82% of its listings carry a review history, median 291 ratings. Tata CLiQ's median badge is 30% on a 1.43x median MRP with nothing above 5x at all — yet only 33% of its listings are rated, and the median count among those is two. The baskets differ, so prices are not ranked. Nothing was bought.

Markers, highlighters and document files read on both marketplaces on 25 October 2026: 41 Amazon listings and 206 Flipkart listings. Here Amazon is the inflated shelf — a median stated MRP of 2.87x the selling price against Flipkart's 2.10x, and a 65% median badge against 52%. Three hours earlier, on home medical devices, the same two retailers ran 1.88x and 2.79x — the other way round. Neither marketplace has a pricing posture; the category sets it. Sixteen stated MRPs cover Amazon's whole stationery shelf, with Rs. 999 on eight listings. Flipkart's review coverage here is the weakest of the run: 57% of listings rated, median 72 ratings, against Amazon's 95% and 467. Nothing was bought or tested.

Flipkart's "treadmill" and "exercise cycle" results read on 25 October 2026: 172 listings, of which 105 are home cardio machines from Rs. 1,081 to Rs. 50,273. Ranked by stated MRP as a multiple of the selling price, the shelf runs 1.8x to 9.2x, median 3.2x - and the multiple shrinks as the machine gets serious: 2.5x above Rs. 25,000, 3.9x between Rs. 2,500 and Rs. 6,000. Six near-identical mini pedal exercisers at Rs. 1,081 to Rs. 2,285 claim list prices from Rs. 2,999 to Rs. 9,999, producing badges of 46% and 89% on the same kind of device - and the cheapest one makes the boldest claim. One walking pad is listed twice, Rs. 798 apart, under a single rating pool. Peak HP is not continuous HP. Nothing was bought, assembled or run on.

A living calendar of every Nykaa sale in 2026: rolling brand days now, Diwali Dhamaka expected 25 Oct-4 Nov, and Pink Friday - the year's deepest beauty discounts - expected 21-28 November. Includes which event is genuinely cheapest for mass vs luxe beauty, how bank offers stack, and past-year patterns. Re-verified weekly; expected windows are replaced with official dates the day Nykaa announces them.

Nykaa's "concealer", "compact powder" and "mascara" results read on 25 October 2026: 54 listings, every one rated, badges from 4% to 57% with a median of 20%, prices Rs. 67 to Rs. 4,725. The discount forms an arch across the price range. Blue Heaven, the cheapest label at Rs. 67-128, runs a median 6% badge. Lakme, one step up at Rs. 142-279, runs 52% and holds both of the read's 57% badges. At the top, M.A.C at Rs. 2,571 and Charlotte Tilbury at Rs. 4,725 run 15% and 10%. The deepest cutting is where the brands are most interchangeable. All six Insight Cosmetics listings are badged exactly 10% - a list-price habit, not a sale. Rating counts are shade-pooled by Nykaa and flagged as such. Nothing was bought or swatched.

Pulse oximeters, nebulizers and BP monitors read on both marketplaces on 25 October 2026: 86 Amazon listings and 201 Flipkart listings. Three Amazon nebulizers advertise 99% off on a stated MRP that is exactly one hundred times the selling price — Rs. 1,198 against Rs. 1,19,800, Rs. 123 against Rs. 12,300, Rs. 879 against Rs. 87,900. We excluded those outliers from every figure here. With them gone, Amazon is the restrained shelf: a median stated MRP of 1.88x against Flipkart's 2.79x, a median badge of 47% against 64%, and rating coverage of 95% against 84% with a median review base of 708 against 174. The baskets differ, so no retailer is named cheaper. Nothing here is medical advice and no device was tested for accuracy.

Amazon's "jump starter", "dash cam", "tyre inflator" and "car vacuum cleaner" results read on 24 October 2026: 106 listings, Rs. 209 to Rs. 33,249. Jump starters run Rs. 399 to Rs. 33,249 (median Rs. 5,339), dash cams Rs. 2,099 to Rs. 18,499, tyre inflators Rs. 209 to Rs. 5,799 and car vacuums Rs. 274 to Rs. 4,799. Seventeen listings carry a 99% badge, and on sixteen the stated MRP is exactly 100 times the price - Rs. 4,299 against Rs. 4,29,900 - which is a rupees-to-paise units error, not a price cut; four more state an MRP below their price. Three different products share the jump starter query: the Rs. 399 result is cables, the first real booster is Rs. 1,999. And across all four shelves the deepest badges sit on the thinnest review histories. Nothing was bought or fitted.

AJIO's "women kurta", "men sweatshirt" and "women handbag" results read on 24 October 2026: 186 listings under 166 distinct product names, prices Rs. 169 to Rs. 3,549, badges 6% to 89%. Twelve names are used by more than one listing, covering 32 of the 186. The largest is "AVAASA MIX N' MATCH Women Floral Print Straight Kurta", the title of six separate listings at Rs. 289, Rs. 305, Rs. 329, Rs. 341, Rs. 347 and Rs. 354. We checked: these are six visibly different garments, not one listed six times - so the finding is that the name does not identify the product. The badge does not order them either; the deepest (49%) sits on the Rs. 305 tile, not the Rs. 289 one. AJIO published no star rating on any of the 186 listings, so the photograph is the only thing that distinguishes them. Nothing was bought or worn.
