PriceSentry: Competitor Prices

PriceSentry tracks the exact competitor product you choose. Paste its URL and we check the live price and stock daily, emailing you the moment anything changes.Most trackers fail two ways: they auto-match the wrong product, then go quiet when something breaks. PriceSentry fixes both — you pick the exact product (no fuzzy drift), and failed reads are flagged, never shown stale.Start free with 1 product; paid from $19/mo. Optional Repricer auto-adjusts prices with guard rails.
