Price Observations by Product

Each row shows the range of prices real users reported for the same product. A high spread means different users saw meaningfully different prices — a potential sign of personalized pricing. Rows with fewer than 5 reports are shown at reduced opacity and should be treated as early signals, not conclusions.

Price Spread by Product

Price spread measures how much prices vary across reporters for the same product. Zero means everyone saw the same price. Higher values warrant closer investigation.

How we measure price spread: spread = (highest reported − lowest reported) ÷ lowest reported × 100. A spread above 15–20% is a candidate surveillance pricing signal. We also detect temporal anomalies — cases where two or more users saw prices differing by more than 10% within the same 30-minute window, which controls for legitimate algorithmic repricing over time.
