PriceHistoryX

Price history charts & deal alerts for Amazon, Walmart, Target, and Best Buy.

PriceHistoryX tracks the real prices of products you visit on Amazon, Walmart, Target, and Best Buy — so you always know when you're getting a true deal. HOW IT WORKS - Visit any supported product page → PriceHistoryX automatically records the current price. - As prices change over time, you build up a private price history. - A deal-score badge appears on the product page showing Lowest / Average / Highest price and how today's price compares. - Track a product to get browser notifications when its price drops by a configurable threshold. PRIVACY-FIRST - All price data is stored locally on YOUR device — never on our servers. - No telemetry, no tracking, no analytics, no ads, no account required. - The extension only communicates with: the retail sites you visit, and api.freemius.com (for license verification, only if you upgrade to a paid plan). - Full privacy policy: https://excesspronet.com/privacy-policy/ SUPPORTED RETAILERS - Amazon (.com, .com.au, .co.uk, .ca, .de) - Walmart - Target - Best Buy PRICING - Free: Track up to 5 products, 30-day price history, Amazon only. - Starter ($3.99/mo): Up to 100 products, 180-day history, all 4 retailers, push alerts. - Pro ($8.99/mo): Unlimited products, 1-year history, deal calendar.
