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.

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.

On this shelf the discount is arithmetic, not a markdown. We read 126 AJIO listings on 17 October 2026 and 29 are badged exactly 70% — for 26 of those 29 the price is the stated MRP times 0.3, rounded up to the rupee: Rs. 499 becomes Rs. 150, Rs. 1,699 becomes Rs. 510. Two houses supply 18 of them and neither carries any other badge. Meanwhile not one of the 126 listings publishes a star average or a rating count, so there is no evidence to weigh against any claim. Badges run 6% to 87%, prices Rs. 150 to Rs. 6,600, and eleven tiles state the same Rs. 1,499.

One bag, one claimed list price, two sites. We read 66 Flipkart backpack tiles and 40 AJIO backpack listings on 17 October 2026. The ARISTOCRAT NRG states an identical Rs. 2,250 MRP on both and sells at Rs. 625 on Flipkart and Rs. 671 on AJIO — while the badges differ by two points. Across the shelf Flipkart's median is Rs. 574 against Rs. 1,061, the reverse of the same two sites' shirt result that morning. And two Flipkart tiles of one Rs. 589 bag both publish 728,911 ratings while duplicates of other bags publish none.

The number most shoppers compare on does not exist here. We read 214 Uniqlo India listings on 17 October 2026: 152 of them — 71% — publish one price and no second figure, so no discount percentage appears at all. Where one does, it is Uniqlo's own earlier price under a limited offer, median 33.5%. Every one of the 214 prices ends in 90, and 40 listings sit at exactly Rs. 1,490. Read the same morning: AJIO's median shirt badge was 70% and Myntra's 64%. Three shelves, three conventions, one incomparable percentage.

An identical rating count on two listings is the duplicate-listing fingerprint, and this shelf is full of them. We read 53 Myntra nightwear listings on 17 October 2026, and twenty of them sit inside six shared rating pools — five tiles all publishing 4.26 stars from 21,875 ratings, five more all publishing 4.33 stars from 22,434, three at 2,059 and so on. Inside the 21,875 pool, four tiles sell at Rs. 399 against a stated Rs. 1,999 and one at Rs. 389 against a stated Rs. 2,999 — same evidence, a thousand rupees of difference in the claim. Prices run Rs. 319 to Rs. 1,359, badges 0% to 87%, and four listings publish no rating at all.

On a large part of this shelf the discount is arithmetic. We read 234 AJIO kurta-set listings on 17 October 2026, and every one of the 24 badged exactly 49% prices at the stated MRP times 0.51, cut to the rupee — Rs. 999 becomes Rs. 509, Rs. 1,499 becomes Rs. 764, Rs. 1,999 becomes Rs. 1,019. One house supplies 21 of them and eleven of its listings sell at exactly Rs. 509 against exactly Rs. 999. Elsewhere, fourteen listings from four unrelated houses state the identical Rs. 4,345 while selling Rs. 652 to Rs. 1,068. 161 of the 234 tiles sell under Rs. 1,000, badges run 15% to 90%, and not one listing publishes a rating.

Two sites, one category, one morning. We read 53 Myntra and 190 AJIO women's nightwear listings on 17 October 2026. At the shelf level they are level: median Rs. 524 against Rs. 538. Hold the brand still and it flips — ICHAA is 21% cheaper on Myntra (median Rs. 379 vs Rs. 479) while MAX and Marks & Spencer are cheaper on AJIO. And the same ICHAA sets state Rs. 1,999 on Myntra against Rs. 5,970 on AJIO while selling within twenty rupees of each other. 49 of Myntra's 53 listings publish a rating count; 0 of AJIO's 190 do.

The phrase 'room air purifier' covers Rs. 449 and Rs. 29,900 on this shelf. We read 94 distinct Flipkart listings on 17 October 2026 across two queries. Five separate sellers list USB mist devices at Rs. 439–449 against an identical stated MRP of Rs. 4,490, every one badged 90%, and not one publishes a single rating — two of the five even share a photograph byte for byte. Higher up, five models from one house, Rs. 6,990 to Rs. 19,989, all publish 4.2 stars from the same 1,825 ratings, and the two shallowest badges in the read, 10% and 8%, sit on the best-known machines. No claim here about filtration, air quality or health.

Same wattage, same cap, 3.4 times the money. We read 70 Amazon LED listings on 17 October 2026, and the seven plain single 9-watt bulbs in them sell from Rs. 42 to Rs. 142. The Rs. 42 tile advertises 77% off a stated Rs. 179; the Rs. 142 tile advertises 5% off a stated Rs. 150 — the cheaper bulb claims the higher list price, which is the whole reason its badge is deeper. A pack of six works out at Rs. 84.17 a bulb against a claimed Rs. 500 a bulb. Above that, sensors cost 3.8x a plain 9W and rechargeable cells up to 14.3x, and the tile with the largest rating pool on the shelf — 35,842 ratings — carries one of the shallowest badges on it.

A sixth of this shelf is the same garment listed again. We read 64 Myntra tiles on 17 October 2026, 32 shirts and 32 blazers, and sixteen of them are five products repeated: five identical tiles at Rs. 451 with no rating on any copy, four at Rs. 626 of which three publish the same 19,208 ratings, three at Rs. 4,224 none of them rated. Two shirts from one house sell at the identical Rs. 459 and are badged 71% and 77%, because they state different MRPs. And the cheapest tile here, Rs. 447, carries 232,259 ratings — more than all 32 blazers put together. No stated MRP is called false.

Two sites, one category, one morning. We read 80 AJIO and 32 Myntra men's formal shirt listings on 17 October 2026. AJIO is cheaper throughout — floor Rs. 120 against Rs. 447, median Rs. 562.50 against Rs. 637.50 — and its median badge is 70% against 64%. But not one of AJIO's 80 listings publishes a star average or a rating count, while 24 of Myntra's 32 do, the deepest carrying 232,259. The one brand on both shelves states an identical Rs. 2,088 MRP and sells Rs. 41 apart. And on both sites the deepest badges sit on the least-known houses.
