Stable Recorded Prices: Products With No Change Across Multiple Observations
Using the published product histories, 3,476 products have at least five observations with no recorded price change, and 3,885 have at least four. “Flat” means every point in the exported history series is the same value.
The short version
Key findings
- 3,476 products have ≥5 identical observations.
- 3,885 products have ≥4 identical observations.
- These cohorts are smaller than the count of products that look flat only when comparing first and latest prices.

“Flat” means every recorded price in the product’s history series is the same value. This is not a claim that shelf prices never changed between observations.

Evidence
What the data shows
- How many products stayed at one updated value across a defined number of observations.
- A sample of long flat histories with date ranges.
Boundaries
What the data does not show
- That 4,085 products stayed flat “across five observations”, that statement is not supported by this export.
- Prices between observation dates, or future stability.
Editorial standards
How this report was checked
- Every headline figure is locked to the published export. The build compares the numbers in this report against the data files and refuses to publish the page if they disagree, so the text and the dataset cannot drift apart.
- Interpretive wording is written and reviewed by a person before a report is approved for publication. Figures are computed, never hand-typed.
- Reports are published after an update is added to the site. Updates are irregular rather than on a fixed weekly schedule, and every report states the dates it covers.
- Corrections are made on this page rather than quietly replaced. If a figure is restated, the change is listed below with its date.
Revisions
- Sep 28, 2026 Restated for the 28 September 2026 observation: 3,476 products have at least five identical recorded prices and 3,885 have at least four, using the full published histories.
- Sep 1, 2026 Restated for the 1 September 2026 observation: products with at least five unchanged observations rose from 3,193 to 3,238, and those with at least four from 3,306 to 3,790, as the new observation extended flat histories for products whose recorded price did not change.
- Aug 16, 2026 Restated for the 16 August 2026 observation: products with at least five unchanged observations rose from 2,433 to 3,193, and those with at least four from 3,271 to 3,306, as another update added a flat observation to products already steady.
