Monday 14 September 2026
Sent at eight on a Monday with a link to the tabs behind it. Nothing on this sheet was decided by the module; everything on it was measured by it.
Changes worth reading
133
Out of 211 differences on the shelves. The other 78 were a lira or two, which is a seller fiddling with the last digit.

₺1,463,754 of the last four weeks' sales sit behind them. Being dearest is a decision, not a fault — this is here so it stays a decision.
What the week was
Computed- Mill & Ember started a sale on 32 listings this morning, cut to one depth — 11% off. 7 of 32 land on shapes we sell, the heaviest of them House Blend 1 kg at ₺1,090 on our side.
- 3 rules fired this week and the one judged so far was called useful. Only an exact barcode match is allowed to ring a phone; a likeness informs the briefing and goes no further.
- We are on the first page of 7 of the 9 watched words on merit, down from 8 last Monday. On 2 of them the slot a shopper sees is one we pay for —
filter coffee beanssits at 4th because of a bought slot and 26th on merit. - 7 products sit above the band around them, with ₺1,463,754 of the last four weeks' sales behind them. 6 of those have been outside it every morning since the store opened on 16 Jun.
- Nothing here changed a price. N11 did not answer this morning, so 43 listings on this sheet are Sunday's and marked as such wherever they appear.

Above the band is where a specialty roaster usually belongs. This section is here so that staying there is a decision somebody makes on a Monday rather than something nobody noticed.
The shelf
Shelf scan- On the first page of 7 of the 9 watched words on merit, against 8 last Monday.
- “filter coffee beans” on Trendyol: 11 to 26. Down 15 places on merit, while the slot we pay for sits at 4.
- “cold brew coffee” on Trendyol: 15 to 18. Down 3 places on merit.
- “espresso beans 1 kg” on Hepsiburada: 14 to 12. Up 2 places on merit.
- “filter coffee beans” on Trendyol: 4th on the page, 26th on merit. That gap is a budget question, not a listing one.
- “hand coffee grinder” on Hepsiburada: 5th on the page, 9th on merit. That gap is a budget question, not a listing one.
What we do not carry
Computed- 6 shapes the watched sellers carry and we do not: coffee capsules, a pour-over dripper, a gooseneck kettle.
- 5 more may already be ours under another size or name — cold brew concentrate, 500 ml against our Cold Brew Concentrate 1 L, and 50% is not sure enough to call either way.
- 4 of the 15 ever raised have been closed. The last one: “We do not flavour coffee. Three of them sell it and they are welcome to it; it is not a gap, it is a different shop.” — Category owner, 22 Aug.
What their buyers complain about
Review scan- Sediment Coffee — bottles leaked in transit, in 9 of the 41 low-star reviews read. Ours ship in a moulded tray. It is worth a photograph on the listing before their cold brew box is a week old.
- Northbound Coffee — roast date already old on arrival, in 6 of the 28 low-star reviews read.
- Copper Kettle — tastes flat or stale on arrival, in 37 of the 210 low-star reviews read. Every bag we send carries the roast date on the front and we do not ship anything roasted more than ten days ago. That is a sentence we are allowed to put on a listing.
- Rookery Roasters — parts missing from the box, in 11 of the 96 low-star reviews read. We ship the starter set with a printed card and a spare paper pack. It is the reason the set costs what it costs.
Each of these carries the number of reviews it was found in. A complaint found once is kept as one review and never printed here as a pattern, and no reviewer’s name, profile or picture is stored anywhere.
What this sheet could not see
Computed- How much any of them sold. No marketplace publishes units, and nothing on this sheet should be read as a guess at somebody's revenue.
- How deep a rival's stock is. In stock or not, and nothing else.
- Why a rank moved. The page never says, and this module does not invent a reason.
- What happened on N11 this morning, which did not answer.
What this sheet is counting
ComputedSample data. Every figure on this sheet is the same model the tab behind it draws from — the matcher, the bands and the ranker — read at 2026-09-14, 05:30. No price of ours or anybody else's was changed by this module, which has no way to change one.
