Record normal prices
For each product and retailer, keep one in-stock price for each day from August 25 to November 22.
Before Black Friday
We are recording prices now so we can check November’s deals later.
We do not have Black Friday results. This issue shows the baseline we have collected and the test we plan to run.
What we have
A growing record of normal prices.
What we do not have
Any Black Friday 2026 sale results.
Baseline status
These counts come from live retailer checks. Seed prices are not included.

Ready for the study
—
“Ready” means the same product has at least 20 live checks from two retailers. The final study also needs enough days in the baseline window.
A real baseline
This graph shows the retailer series with the most live checks in the current study categories. It is one offer, not a market result.
Coverage
We want eight products in each category. Each product needs live prices from at least two retailers. The graph shows the gap.
What we plan to do
For each product and retailer, keep one in-stock price for each day from August 25 to November 22.
Find the lowest in-stock price from November 23 to November 30.
Report the saving against the 90-day median, whether the sale set a new low, and how long the lower price lasted.
What counts
Current limits
Too few products have two working retailer sources. Some retailer checks are blocked or stale. We also do not have the full 90-day baseline yet.
If too few products meet the rules after the sale, we will publish the missing-data report instead of a market-wide claim.
Why test this?
Which? checked 175 Black Friday deals from 2024. Every product was cheaper or the same price at another point in the surrounding year. RunRepeat also found that the sneakers in its study were cheaper on most other days.
Those studies explain the question. They do not tell us what the 2026 GetPriceOf data will show.
