Get instant alerts when PS5 and other items are back in stock. Runs locally. Beat the scalpers. Beat the scalpers. Shop at your price. CartFox is a privacy-friendly Chrome extension that watches for restocks and lets you know when a product becomes available. Spend less time refreshing tabs and give yourself a better chance to buy at retail. Choose a supported product, select your stores, and set your maximum price. Looking to pay MSRP? Set that as your limit. ShopFox checks availability and sends a desktop notification when it finds a match, so you can head to the store and complete your purchase. Restock alerts, right in Chrome. Keep your watchlist in one place, choose how often to check, and pause tracking whenever you want. Your browser does the checking while Chrome is running and your computer is awake. Your watchlist. Your business. CartFox has no telemetry, analytics, or tracking pixels. Your watchlist, preferences, and alert history stay in your browser’s local storage. Stock checks run on your device, without a cloud monitoring service collecting your shopping activity. No account required. Get started without handing over an email address or creating another password. Free where it matters. Our core functionality is free and will stay free. We don’t currently make money from ShopFox. In the future, we’ll let the community help shape optional features they’d pay for, or explore affiliate commissions through retailer partnerships. Availability and prices can change quickly. Alerts depend on your checking interval and the retailer’s response, and don’t reserve stock or guarantee a purchase. Find your next restock with ShopFox
