What is Amazon Auto Buy?
Auto Buy is a price-triggered purchase. Instead of only alerting you when a price falls, Amazon completes the order for you when the target is met. Modern Retail reported the launch on November 13, 2025, as part of Amazon's Black Friday and Cyber Monday push, describing it as available to all US Prime members through the Amazon app.
It grew out of Amazon's AI shopping assistant. Amazon renamed Rufus to Alexa for Shopping on May 13, 2026, and Amazon's own feature overview now lists price history, price alerts and auto-buy among the assistant's tools.

How Amazon Auto Buy works
Amazon says the assistant checks prices regularly; Modern Retail reported Amazon describing checks every 30 minutes, so shoppers do not need to stay logged in or refresh the page. When the price reaches the target, the order is placed with the default payment method and shipping address on the account.
Consent is built in: before anything is set, the shopper confirms the price details by ticking an Auto Buy box. Amazon then sends an order confirmation like any other purchase.
- Shopper sets a target price or discount
- Shopper ticks the Auto Buy box to confirm
- Amazon monitors the price in the background
- Order is placed automatically when the target is met
- Confirmation arrives and the order appears in Your Orders
How to set up Auto Buy, step by step
Auto Buy is set from the Amazon Shopping app. Reports say price alerts cannot be set on the website, so use the app.
- Open the product page in the Amazon Shopping app
- Open the assistant chat, or tap Price history
- Choose Set price alert, or ask it to buy at a set price or discount
- Enter your target price
- Tick the Auto Buy box to allow the automatic purchase
- Check your default payment method and address are current
Auto Buy limits and rules reported so far
Amazon has not published a full rules page in the coverage we reviewed, so treat the details below as reported rather than official. Doctor of Credit reported in January 2026 that Auto Buy only works on items fulfilled by Amazon and that coupons and promotional discounts are not applied. Seller news coverage added that each request covers one unit and one active request per item.
The practical point for shoppers: the trigger is the listed price, not a clipped coupon, so a coupon-driven deal may not fire your Auto Buy.
- US Prime members, Amazon app
- Reported: Amazon-fulfilled items only
- Reported: one unit and one active request per item
- Reported: coupons and promotions not applied
- Uses default payment method and address
How to cancel an Auto Buy order
You can delete a price request before it triggers from the assistant or your price alerts. If an order has already been placed, Modern Retail reported fine print giving shoppers 24 hours to cancel before the item ships. After that, the normal Amazon return policy applies, so an unwanted Auto Buy order can still be returned within the standard window.
Auto Buy vs price alerts vs Subscribe and Save
A price alert only notifies you. Auto Buy acts on the alert. Subscribe and Save ignores price targets and ships on a schedule with a fixed percentage discount, while Amazon Buy Again is a manual reorder list. Shoppers who buy the same item regularly but care most about price may now prefer Auto Buy; shoppers who want reliability prefer a subscription.
Three ways shoppers rebuy
| Auto Buy | Subscribe and Save | Buy Again | |
|---|---|---|---|
| Trigger | Target price hit | Schedule | Shopper taps |
| Discount | Price drop | Up to 15% | None by default |
| Coupons | Reportedly not applied | First order only | Applied |
| Best for | Price watchers | Regular use | Occasional rebuys |
What Auto Buy means for sellers
Auto Buy changes when demand shows up. Shoppers who would have browsed and left now leave a standing order at a price below today's. When your price drops to that level, those waiting orders can convert together, which can create a sudden spike in units.
That has three consequences. First, price cuts can drain inventory faster than your normal sell-through suggests. Second, because coupons reportedly do not trigger Auto Buy, a list price reduction reaches these shoppers while a coupon may not. Third, buyer intent becomes less visible: the conversion happens without a fresh search or ad click.
- Expect unit spikes when price crosses common targets
- List price changes reach Auto Buy shoppers; coupons may not
- Fewer last-minute ad clicks before the purchase
- Stock levels matter more during deals
Pricing strategy in an Auto Buy world
Avoid deep, short price dips you cannot support with stock. If a temporary price cut triggers a wave of Auto Buy orders and you run out, you lose rank and the Buy Box at the same time. Plan deal prices with inventory cover in mind, and keep prices consistent with Amazon's fair pricing policy.
Repricing tools also need care. An algorithm that drops your price briefly to win the Buy Box can now trigger many automated orders at the lowest price in the cycle. Our guide to Amazon dynamic pricing explains how to set floors that protect margin.
Make listings readable to AI shopping tools
Auto Buy starts in an AI conversation, so the product has to be easy for the assistant to understand. Clear titles, complete attributes and plain-language benefit statements help the assistant match a shopper's request to your listing. Amazon said at Accelerate 2026 that shoppers increasingly describe problems in everyday language, which rewards sellers who explain clearly what their products do.
