Amazon Rufus Auto Buy turns discount history into stored purchase intent
Vanessa Hung has published an analysis of how Amazon's Rufus Auto Buy: live for all US Prime members since November 2025: changes the strategic implications of promotional pricing. Auto Buy lets shoppers set a price target; Rufus checks every 30 minutes and executes automatically when the price hits that number.
What changed
Shoppers use the 30- and 90-day price history surfaced in Rufus conversations as their reference point: meaning every public promotion becomes a reference price that stored-demand targets may anchor to permanently.
Why it matters for advertisers
For you, this means auditing the lowest public price per ASIN over the last 12 months and structuring future discounting through closed channels such as Subscribe and Save or virtual bundles rather than public promotions where possible, to avoid permanently setting the floor at which Auto Buy targets will execute.
