We checked 125 Lightning Deals this week. 13 were real.

01 / The number13 out of 125.

Amazon's UK Lightning Deals feed, pulled twice a day; every live deal put through the same gates as everything else on this site, within the hour of going live and again through its run; a verdict recorded on each one. This is what the week looked like.

About one in ten. The other 112 carried the same countdown, the same “% claimed” bar and the same red badge as the 13 that were. Nothing on the page tells them apart. Only the history does.

02 / The receiptsAmazon's percentage next to the real drop.

The “not really a deal” pile, biggest badge first. Amazon's badge is measured against the price it was listing immediately before the deal. “Usual” is the median of the product's recorded daily prices over the last year. “Real drop” is the deal price against that.

The biggest badge in the pile was “32% off” on the KitchenAid Pasta Roller 5KSMPSA: a product that usually sells for £54.47, offered at £57.99. That is £3.52 more than it normally costs, under a red badge.

Anker turned up twice in this pile, each a few percent under a listed price that is itself the everyday price. Repeat appearances are the tell: a product that is in the countdown every week is not having a sale.

None of this is illegal, and we are not suggesting it is. A reference price only has to be a price recently charged. That is a lower bar than “the price it usually sells for”, and the gap between the two is where these badges live.

03 / The real onesWhat a genuine low looked like this week.

Eight of the 13, to show the other side of the ledger:

• Ecobam Window Squeegee Cleaning Equipment Kit — £13.00. Usually £19.99; 63% under its verified reference. Amazon's badge said 19%, which undersold it: the listed price had already drifted down before the deal.
• Wantdo Women's Plus Size Swimwear One Piece Tummy Control… — £14.96. Usually £26.97; 50% under its verified reference.
• lifemet Solar Highland Cow Garden Ornament — £15.98. Usually £25.49; 44% under its verified reference. Amazon's badge said 20%, which undersold it: the listed price had already drifted down before the deal.
• SMENG Women's Shorts Summer Solid Colour Workout Casual Dr… — £14.24. Usually £18.99; 43% under its verified reference.
• FLEXISPOT CylineE Electric Standing Desk Frame with Round… — £93.49. Usually £109.99; 38% under its verified reference. Amazon's badge said 15%, which undersold it: the listed price had already drifted down before the deal.
• LAFROI Men's Long Sleeve UPF 50+ Baselayer Skins Performan… — £12.74. Usually £17.49; 36% under its verified reference. Amazon's badge said 15%, which undersold it: the listed price had already drifted down before the deal.
• Duronic MF500 BK Electric Milk Frother — £29.74. Usually £41.49; 34% under its verified reference.
• VGRPRO Cordless Hair Clippers Men and Trimmers Set — £39.99. Usually £49.99; 33% under its verified reference. Amazon's badge said 20%, which undersold it: the listed price had already drifted down before the deal.

Each became an ordinary DropSignal deal with its own page, chart and score, carrying a Lightning badge with the end time. Where the link still works, the deal is still live; where it has gone, so has the price.

04 / Near missesReal drops that didn't make the cut.

A price can be genuinely low and still not be something we'd put in front of you. 27 fell here this week; the biggest four:

• GOZNEY Pizza Server 18" — £44.99. A real drop — 36% under the verified reference, usually £55.99 — but it didn't clear our quality bar: Home already holds 19 of 63 live deals (cap 30%)
• mantic Halo: Flashpoint Recon Edition — £30.00. A real drop — 29% under the verified reference, usually £43.87 — but it didn't clear our quality bar: held for review — niche category "Uncategorised"
• BLUEGO 2000ml Borosilicate Glass Water Bottle with Stainle… — £24.01. A real drop — 25% under the verified reference, usually £29.82 — but it didn't clear our quality bar: score 40 below the 65 bar (niche category "Sports & Outdoors")
• GUNDDIYCLUB Mini Vortex Mixer — £58.18. A real drop — 22% under the verified reference, usually £74.99 — but it didn't clear our quality bar: score 49 below the 65 bar (niche category "Business, Industry & Science")

The reason is always written next to the deal on the Lightning Deals page: a low score, thin recent history, an odd-size listing, or a category that already holds its share of the site. We list them with the reason rather than pretend they aren't there.

05 / The honest gapThe ones we couldn't call.

58 of the 125 got no verdict, for two reasons we think are worth being open about.

Too little history (43). Many Lightning Deals are on products listed weeks ago. With fewer than fourteen days of recorded prices, “usual price” doesn't mean anything yet, so we say “can't tell” rather than guess. Inconvenient, and correct.

A price we couldn't confirm (6). The deals feed said one price; a live check of the product said another, higher. Feed prices are hours old. When the two disagree in the direction that would flatter the deal, we don't publish a verdict on a number the page isn't showing.

06 / MethodHow we counted.

• Window: Friday 4 September, 18:00 to Friday 11 September, 18:00. Amazon's UK Lightning Deals feed pulled twice a day; every live deal checked within the hour and re-checked at least every six hours, and its latest verdict is the one counted.
• Each deal evaluated against its own recorded price history (via Keepa), using the published DropSignal methodology: history-capped reference, median test, 14-day minimum, live product check.
• “Genuine low” means it cleared every gate and was published as a normal deal. A deal that ran more than once in the week counts once.
• Products in the receipts are named because the numbers are matters of record; we have no view on their quality.

The live version of all of this, every deal and every verdict, updated through the day, is on the Lightning Deals page. The longer explanation is in Are Amazon Lightning Deals actually good deals?

07 / The rate so far2 data points.

Edition 1: 5 of 40, 13%. This week: 13 of 125, 10%. The same shape again: most of what the countdown format sells is not a low. We'll keep counting, and the interesting question is whether the rate moves before Prime Big Deal Days in October and Black Friday in November. If you want the real ones as they appear rather than on a Friday, they hit the free Telegram channel the moment they clear the gates.
