SAS Price Sentinel

Monitor Amazon Subscribe & Save price changes to avoid silent hikes

Problem

Users with Amazon Subscribe & Save subscriptions may see prices increase without notice. By the time the email arrives, shipping is near, making it hard to compare history or cancel in time. One user called it dissociative.

Solution

Users import their Subscribe & Save items, and the service periodically scrapes prices and keeps history. When price exceeds a threshold or jumps abnormally, it alerts via email/push and provides a one-click link to manage the subscription on Amazon.

Users

Household users who frequently use Amazon Subscribe & Save

Why now
