Amazon's Alexa shopping tools can monitor product prices and automatically purchase items when they reach specified price targets, removing the need for manual price checking. This represents how e-commerce platforms increasingly leverage artificial intelligence to simplify the shopping experience for consumers.

The Price History tool displays price fluctuations over 30, 90, or 365 days, helping customers set realistic price targets before enabling price alerts or auto-purchases. To use auto-buy, eligible Prime members can ask Alexa to purchase an item at a specific price using their default payment method, though the feature doesn't support coupons or promotional discounts. Third-party services like CamelCamelCamel and Keepa offer alternative price tracking, though they cannot place orders. The service is currently available to US customers via the Amazon app, Amazon.com, or Echo devices.
