What an observed listing price tells you

A competitor's listed price is evidence, but not of what most people think. Learn precisely what it establishes, what it merely suggests, and what it cannot establish at all.

What this lesson teaches

  • State the three distinct facts a listing price does and does not establish
  • Use the distribution of observed listings rather than the lowest one
  • Avoid the two inferences that reliably mislead

Suppose you observe that six sellers list a comparable item at £24.99, £26.00, £27.50, £29.99, £31.00 and £49.00. What have you learned?

What an observed price does establish

What it does not establish

Read the distribution, not the minimum

The instinct is to anchor on £24.99, the lowest. The lowest observation is the least informative one: it is the most likely to be an error, a clearance, a loss-leader, a different specification, or a seller about to exit. The median of the six observations here is £28.75 and the interquartile span runs from about £26 to £31. That span is the useful object. It says roughly where the market has settled and how wide the acceptable band is, and a wide band is itself information — it means buyers are not choosing on price alone, which is the condition under which anything other than being cheapest can work.

The same six observations, read two ways.

Lowest observed is £24.99We must sell below £24.99Poor. Anchors on the single least reliable point and ignores your costs.
Median £28.75, band £26–£31, one outlier at £49A £29 listing sits inside the band; £49 shows the band is not hardSound, and it leaves the pricing decision where it belongs — with your landed cost.

Record the observation, not the conclusion

Store what you saw, where, and when: the URL, the price, the date it was retrieved. Prices change and memories reshape themselves to fit decisions already taken. An observation with a date can be re-checked; a remembered impression cannot.
