We read Nykaa's perfume, face serum, body lotion and night cream listings on 26 September 2026 - 72 of them, with 22 seated here. This is the most-evidenced shelf we have read: every one of the 72 publishes a star average and a rating count, 3,367,649 ratings between them. But the evidence runs in the opposite direction to the price. The 35 listings under Rs. 500 carry a median 17,641 ratings each; the eight over Rs. 5,000 carry a median of 158 - a 112-fold gap. A Rs. 169 bottle has 95,849 ratings; a Rs. 10,710 one has 16. All eight designer bottles wear exactly 15% off, and the shelf's median badge is 12% on serum. One serum's 103,377 ratings appear on two listings at two prices.

We read Amazon's walnut, pistachio, raisin, makhana and dates shelves on 26 September 2026 — 150 distinct listings, of which 137 print Amazon's own per-100g rate, so the unit arithmetic is done for you. The spreads inside a single search are large: dates run Rs. 290 to Rs. 1,790 a kilo (6.2x), raisins Rs. 470 to Rs. 1,810, walnut kernels Rs. 890 to Rs. 2,950, makhana Rs. 770 to Rs. 2,000 and pistachios Rs. 1,390 to Rs. 3,090. Pack size is the biggest lever — a kilo of makhana bought in 200g packs costs about twice a kilo bought in one. On six of the 137, the printed rate and the weight in the title disagree by more than ten per cent. Nothing on this shelf carries a discount badge: there is no MRP to discount from.

We read the perfume shelf on four retailers on 26 September 2026 — 189 listings. Median prices run from Rs. 410 on AJIO to Rs. 1,640 on Tata CLiQ, but those are four different catalogues: no brand appeared on all four shelves, so that gap is about stocking, not overcharging. Where a like-for-like does exist, it is sharp. Wild Stone Edge: Rs. 343 on Myntra against Rs. 400 on AJIO, off the same Rs. 799 MRP. AND Love Muse: the identical Rs. 540, the identical Rs. 1,200 MRP and the identical 55% badge on both — and Myntra publishes 7,721 ratings while AJIO publishes none. AJIO showed no rating on any of its 68 listings; Tata CLiQ showed one on 58 of 72, at a median of six.

We read Vijay Sales' small kitchen appliance shelf on 26 September 2026 - 59 listings across six category pages, each with a selling price and a stated MRP, with 22 seated here. Forty-one of the 59 print a wattage in the title, which makes this one of the few appliance shelves where a unit rate can be computed from published data. Sandwich grillers run Rs. 1.46 to Rs. 5.25 a watt; blenders and grinders run Rs. 3.90 to Rs. 13.99. The sharpest case: a 150W portable blender at Rs. 2,099 costs Rs. 13.99 a watt while an 1,100W bullet grinder at Rs. 4,599 costs Rs. 4.18 - 3.3 times dearer per watt, and Rs. 2,500 cheaper in absolute money. Watts are power draw, not performance, and none of the 59 listings publishes a rating.

We read eleven Vijay Sales category pages on 26 September 2026 — 110 listings, each with a selling price and a stated MRP — and sorted them by how much discount each aisle actually displays. Nutri blenders badge a median 48% off. Electronic safes badge 2%, with the best in that 20-listing aisle reaching only 18%. The underlying rule is price: the cheaper half of the shelf shows a median 42% off, the dearer half 22%. And the mechanism is visible — the declared MRP multiple tracks the badge almost exactly, from 1.93x on blenders down to 1.02x on safes. A category discounts more because its sellers declare a higher MRP, not because the cash price moved. None of the 110 listings published a rating.

We pulled Flipkart's results for "smart bulb", "smart plug" and "smart door lock" on 25 September 2026 — 185 listings — and counted how many titles claim the thing the search asks for. Eight of the 71 smart bulb results state Wi-Fi, app control, Alexa or Google Assistant in their own title. Thirty-six mention a Bluetooth speaker, five are sewing-machine lamps and seven are star projectors. Twenty-four bulb listings share one stated MRP of Rs. 999 across 18 sellers, nine of them selling at the same Rs. 458, and 13 have never been rated. The plug shelf is healthier — 28 of 59 connected, from Rs. 640 — and the door lock shelf spans Rs. 285 to Rs. 25,999 with 15 of 41 unrated.

A tyre inflator advertises its headline spec in its own title, so we counted. We pulled Flipkart's car care results on 25 September 2026 — 194 listings, 56 of them inflators. All 56 print a psi figure, and 42 print exactly the same one: 150 psi. Those 42 sell from Rs. 646 to Rs. 6,999, a spread of 10.8 times behind one identical number. Divide price by claimed psi and the shelf inverts: the Rs. 213 listing claiming 300 psi is Rs. 0.71 a psi with 2,330 ratings, while the Rs. 6,999 one claiming 150 psi is Rs. 46.66 a psi with none. Ten more listings share one description under two brand names and nine model codes, all unrated.

We read both sock shelves on 25 September 2026 - 34 listings on AJIO, 54 on Myntra - and divided every price by the pack count its own title states. AJIO's median pair is Rs. 51.00 and Myntra's Rs. 80.32, so AJIO is about a third cheaper. But the cheapest pair anywhere, an AJIO five-pack at Rs. 17.80 a pair, sits just Rs. 2.62 below Myntra's cheapest - a twelve-pack at Rs. 20.42 a pair that carries 4.4 stars from 354 ratings. And that is the real split: 42 of Myntra's 54 listings publish a rating count, median 148 and up to 9,831, while none of AJIO's 34 publishes one. On both shelves the biggest discount badges sit on the packs that are already cheapest per pair.

We read AJIO's socks, gloves, muffler and thermal listings on 25 September 2026 - 139 with a price and a stated MRP, 21 seated here. Socks are the one item sold both singly and in packs, and dividing by the pack count the title states splits the shelf: 23 multipacks run at a median Rs. 31.67 a pair, 11 single pairs at Rs. 89. The badge runs the other way - 72 per cent on the multipacks, 46 on the singles. One brand sits at both ends: five pairs for Rs. 110, or a single pair for Rs. 550. Declared MRPs cluster on round numbers, with 18 of 139 declaring exactly Rs. 999, which is how a Rs. 39 pair earns a 92% badge. And not one of the 139 listings publishes a rating.

We read both luggage shelves on 25 September 2026 - 91 trolley and suitcase listings on AJIO, 78 on Tata CLiQ - and found eight brands and twenty declared MRPs on both, which makes a like-for-like comparison possible for once. At matched declared MRPs, AJIO is cheaper on every mass brand: a Teakwood Leathers hard shell declaring Rs. 8,199 is Rs. 1,230 against Rs. 1,799, and Aristocrat, Skybags, Benetton, Nasher Miles and Tommy Hilfiger run 8 to 19 per cent cheaper. Mokobara reverses it at all four shared MRPs, where Tata CLiQ is Rs. 501 to Rs. 2,128 cheaper. And neither shelf offers evidence: AJIO publishes a rating count on 0 of 91, Tata CLiQ on 37 of 78 with a median count of three and a maximum of ten.

We read Myntra's watch listings on 25 September 2026 — 80 in all, 64 of them ordinary wristwatches — and sorted them by whether the brand makes watches for a living. The 27 from Titan, Zoop, Casio, Sonata, Fastrack and Timex have a median discount of 0%, with 18 at exactly zero and not one above 50%. The other 37 have a median of 72%, with 25 at 70% or more. Both groups sell in the same money: Anouk's Rs. 1,831 watch wears a 72% badge off a stated Rs. 6,497, while Titan's Rs. 1,995 wears none. And this is not just a new-seller effect: Casio's 0%-off Vintage carries 25,967 ratings, WROGN's 76%-off analogue carries 16,341.

We read the watch shelves at AJIO, Myntra and Tata CLiQ on the same morning, 25 September 2026 — 194 listings. They are not three versions of one shelf. Myntra's median watch is Rs. 995, AJIO's Rs. 1,400, Tata CLiQ's Rs. 2,984; Myntra has 42 listings under Rs. 1,000 and none over Rs. 5,000, while Tata CLiQ has none under Rs. 1,000 and eight over Rs. 10,000. The sharpest difference is not price: not one of AJIO's 80 listings publishes a rating, against 66 of 80 on Myntra. And the watch houses hold their prices on both shops that stock them — Titan is at 0% off on Myntra and 3% on AJIO.

We read Tata CLiQ's candle, vase and wall art listings on 25 September 2026 - 78 with a price and a stated MRP, 57 of them at or under Rs. 2,000, and 21 seated here. This is a shelf with almost nothing published on it: only 17 of the 57 carry a rating at all, ten of those rest on exactly one rating, and the largest sample anywhere is 20. With no evidence to compare on, the badge does as it pleases: two bud vases Rs. 7 apart in price wear badges of 6% and 78%, because one declares an MRP of Rs. 299 and the other Rs. 1,300. Across the shelf the declared multiple runs from 1.07 times the selling price to 5.79 times, and it tracks the label, not the object.

We pulled Flipkart's sanitary pad, panty liner and menstrual cup results on 25 September 2026 and divided every price by the piece count the listing states — 177 listings read, 99 with a count we could read without guessing. One sanitary pad costs between Rs. 3.12 and Rs. 19.90, with a median of Rs. 5.20. The discount badge splits by brand recognition: the 27 familiar-name listings carry a median 40% badge and cost Rs. 6.39 a pad, the 23 lesser-known labels a 65% badge and Rs. 3.95. Twenty-nine listings are Cailin Care 155mm liners under 29 different product names, 27 of them with no rating at all — and on the cup shelf Pee Safe pools one rating count across three sizes while SIRONA publishes three separate ones.

We pulled Amazon's results for "almonds 1kg", "cashew 1kg" and "ghee 1 litre" on 25 September 2026 and divided every price by the weight the listing states — 120 listings read, 106 with a readable figure. A kilo of almonds costs Rs. 899 to Rs. 1,598 (median Rs. 1,128), a kilo of cashews Rs. 749 to Rs. 1,898, a litre of ghee Rs. 299 to Rs. 2,890. The cheap kilo and the low star rating arrive together: almonds under Rs. 1,000/kg average 3.44 stars on a median 18 reviews, those above it 4.02 on a median 2,530. Thirteen listings charge exactly Rs. 999 for a kilo of almonds, rated 2.1 to 5.0, and five Avogro cashew packs share one price of Rs. 879 with ratings of 1.2, 1.9, 2.2, 3.0 and 5.0.
