How Algorithmic Pricing Works
- Algorithmic pricing uses AI to combine personal data and demand signals to predict what an individual will pay.
- It can change prices for the same product between neighbors based on search history, device, location, income inferences, and demand.
Instacart Live Price Check Investigation
- Consumer Reports ran live Zoom price checks with 400 volunteers comparing identical Instacart baskets at the same store and time.
- Volunteers screenshot prices and researchers verified differences to test for personalized pricing in practice.
Magnitude Of Price Variation Found
- The investigation found price variation for about three quarters of grocery items, with spreads up to 23%.
- Differences could translate to roughly $1,200 per year for a family of four on grocery spending.
