Five Indian retailers' own terms and FAQ pages, read 15 November 2026, logged out, nothing bought — 350,947 characters of rendered text between them. Searched for "price match", "lowest price", "price protection", "price guarantee" and "price drop": zero matches in all five. Croma's own /lowest-price-guarantee URL returns HTTP 200 and renders 830 characters of navigation with no policy text. Vijay Sales is the only one that states which price binds — "at the time of order confirmation and payment" — and also states that an order at an incorrect price may be cancelled regardless of whether payment has been taken. Flipkart's terms place price in the buyer-seller contract; Amazon's put it inside the no-warranty clause. Not legal advice.

Amazon India's own newsroom post, published 12 November 2026 and read on 15 November. Alexa for Shopping is rolling out on the Amazon Shopping app and website, and it brings price history to the product page: "Tap Price History on any product detail page, or just ask, to see how a price has changed within a 30-day, 60-day, or 365-day period." Signed-in customers, select storefronts, no Prime membership and no Echo device required. It also adds AI overviews in search, side-by-side comparisons drawing on "public sources", deal alerts, scheduled restocks with a price condition, and basket building from past orders. Amazon says more than 4 million deal alerts were set for its Great Indian Festival 2026. The feature was not tested here.

Sixty-eight Myntra men's kurta and kurta-set listings, read 15 November 2026 from Myntra's own listing data, logged out, nothing bought. Rs. 441 to Rs. 1,773, median Rs. 986, and 37 of the 68 sell under Rs. 1,000. Myntra's own Anouk label states a median MRP of 2.02 times its price and badges 50% or 51% on six of its seven listings, where the other 61 state 3.12 times and badge a median 67%. Anouk is also the dearest label here — median Rs. 1,409 against Rs. 957 — and six of its seven tiles publish no rating at all. At the other end, one kurta asks Rs. 822 against a stated Rs. 4,999: an 84% badge on a 6.08x claim. One seller accounts for 31 of the 68 listings. Nothing was worn or washed.

One hundred and forty-five Tata CLiQ luggage listings, read 15 November 2026 from Tata CLiQ's own listing data, logged out, nothing bought. Divide each multi-piece set by the piece count its own title states and the ladder inverts: Aristocrat's six-bag set is Rs. 1,183 a bag against Rs. 1,649 for the same brand's single small cabin trolley. Skybags' three-case set is Rs. 2,233 a bag against Rs. 3,100 for one of its duffle trolleys; Mokobara's pair is Rs. 5,750 a bag against Rs. 6,999 for its single. Nasher Miles is the exception — its set is Rs. 136 a bag dearer than its own cabin case. The dearest listing of all 145 is a small cabin case at Rs. 19,740, Rs. 3,180 above the same brand's large trolley. 51 listings publish no rating; the highest count anywhere is 26. Nothing was packed, wheeled or flown.

Flipkart's own pages, read 15 November 2026 from India, logged out, nothing bought. flipkart.com/black-friday-sale-store returns HTTP 200 with a Black Friday title, description and keywords — and a body of 1,447 characters containing navigation, footer and Flipkart's own "Oops! Something went wrong" error card. No product, no banner, no date. Flipkart's newsroom at stories.flipkart.com carries no Black Friday post, and its live offers store answers "when is the next sale?" with "starts soon". Black Friday 2026 is Friday 27 November and Cyber Monday is 30 November — calendar dates, not Flipkart's. No date has been invented here, and nothing predicts whether Flipkart will run one.

Thirty-nine Myntra trekking and hiking shoe listings, read 15 November 2026 from Myntra's own listing data, logged out, nothing bought. Rs. 956 to Rs. 3,799, median Rs. 1,699; badges 23% to 81%, median 60%. Twelve listings state an MRP of Rs. 6,699 or more and every one of them sells under Rs. 2,600. Decathlon, the one outdoor specialist here, states the lowest reference prices in the read (Rs. 2,499-5,999, a median 1.61x) and charges the highest actual prices (median Rs. 3,049). HRX states the highest (Rs. 6,699-8,299, a median 4.76x) and charges a median Rs. 1,598. HRX's nine tiles share just three rating pools — and inside one of them the same 404 reviews back a Rs. 1,932 listing and a Rs. 1,399 one. Nothing was worn or walked in.

Black Friday 2026 falls on Friday 27 November, and Cyber Monday on 30 November — calendar facts, not retailer announcements. On 12 November 2026 we fetched the Black Friday URL of nine Indian stores, logged out, from an Indian connection. Amazon's amazon.in/blackfriday loads but is still titled "Black Friday Sale 2025" with nothing in the body but navigation; Myntra's page is titled "Black Friday Sale Live on Myntra 2025" and uses the phrase only in that title. Hostinger is the single store genuinely trading on it, with badges from 33% to 99%. AJIO returned 403, GoDaddy 404 and Nykaa 500 — which proves nothing either way, and this page says so.

Fifty-six Nykaa body wash, shower gel, scrub, bath salt and soap listings, read 15 November 2026 from Nykaa's own listing data, logged out, nothing bought. One coffee body scrub sells under two separate product pages: a 100 g jar at Rs. 382 and a 55 g jar at Rs. 251 — Rs. 3.82 a gram against Rs. 4.56, so the smaller jar is 19% dearer per gram while carrying the smaller badge. Both pages show the identical 182,519 ratings at 4.5 stars. This is a shallow shelf: median badge 20%, median stated MRP just 1.25 times the price, 45 of 56 badging 30% or less and eleven badging exactly 15%. The one 85% badge in the read is a scrubbing glove with the lowest star average on the shelf. Nothing was opened or used on skin, and no efficacy claim is made or repeated.

Thirty-five Nykaa listings for nail polish remover, false eyelashes and lash glue, read 15 November 2026 from Nykaa's own search data, logged out, nothing bought. Prices Rs. 49 to Rs. 743; badges 3% to 74%, median 10%. The cash saving is the figure that matters: median Rs. 27 across the read, and median Rs. 10 across the 17 nail polish removers. Seven of those 17 save Rs. 4 or less, and the cheapest saves exactly one rupee — Rs. 49 against a stated Rs. 50. Three listings from two houses sit on identical numbers: Rs. 89, a stated Rs. 99, badged 10%. Wipe packs of 30, 40 and 50 — Rs. 57, Rs. 76, Rs. 95 — all work out to exactly Rs. 1.90 a wipe, while the dearest costs Rs. 2.97 a wipe on a deeper badge. Six of the nine listings badged 30% or more belong to one lash house, topping out at Rs. 85 against a stated Rs. 325. Nothing was opened or worn.

Nykaa's own pages, read 15 November 2026 from India, logged out, nothing bought, with a real browser running the site's JavaScript. nykaa.com/sp/pink-friday-sale/pink-friday renders Nykaa's own not-found card — "Sorry! We couldn't find the page you are looking for" — and the phrase "pink friday" appears zero times in its 61,753 characters. The homepage is back to its default cosmetics title after carrying named-sale titles through the festive weeks, and the only named thing running is a "BEAUTY BONANZA" strip with no start date, no end date and no percentage. Pink Friday remains expected 21–28 November 2026 — our projection from three years of Nykaa's timing, not a Nykaa commitment. Black Friday itself is Friday 27 November. No date has been invented here.

MakeMyTrip's own offers page, read 15 November 2026 from India, logged out, nothing booked. The sale is live and its three codes all stop on 4 December 2026: TKMSALE (up to 50% off flights, stays, packages, buses, cabs and trains), LIGHTNING (flash deals daily at 6 PM) and TKMFOCUS (selected destinations). Eleven cards share that 4 December deadline. Behind them sit 16 offers that have not started yet, each stamped with its own start date — five within a day, two on 17 November, five on 18 November, two on 19 November, one on 13 December and one on 26 December. Five cards expire 19 November, five on 20 November and ten on 30 November — and one still on the page expired on 30 September. Nothing was booked and no code was redeemed.

Eighty-two Amazon board game, jigsaw and chess listings, read 15 November 2026 from Amazon's own search data, logged out, nothing bought. Rs. 89 to Rs. 7,836, median Rs. 434; badges 2% to 89%, median 38%. Divide each single puzzle by the piece count on its own box and the shelf runs Rs. 40.50 to Rs. 507.14 per 100 pieces — a 12.5x spread, with the cheapest-per-piece puzzle costing Rs. 121 more than the dearest. Five listings from one publisher all sell at Rs. 639 with two different stated MRPs and two different badges, and three of them share an identical 74-rating pool. The best-known publisher badges 2%; unbranded wooden puzzles badge 74% to 85%. Three multi-packs are excluded from the per-piece ranking because their titles will not say whether the count is per puzzle or total. Nothing was opened or assembled.

Amazon's own charger and cable shelf, read 14 November 2026 from India, logged out, nothing bought — 58 distinct listings priced Rs. 89 to Rs. 2,199, median Rs. 309, and not one of them unrated. One search returns three different products: 31 cables (median Rs. 199), 14 car chargers (Rs. 565) and 13 wall adapters (Rs. 649). 44 titles state a wattage, but the number means different things on a cable and on an adapter — which is why a Rs. 199 cable can honestly state 120W while a Rs. 2,199 adapter states 70W. The five best-evidenced listings are all cables under Rs. 230.
