What It Is

SaleCheck is an upcoming browser extension for the Chrome Web Store, focused on tracking prices for Amazon products. After clicking Track Product on a product page, the extension checks the price once per day and shows a badge on the toolbar icon when the price drops. It emphasizes “no account, no email, no pop-ups,” positioning itself more as a quiet price-comparison helper for individual consumers than an enterprise SaaS product.

Core Features and Data Approach

Its main features include product tracking, daily price refreshes, price-drop alerts, 90-day historical price comparisons, savings statistics, and Pig World milestone rewards. Deal Intelligence is the standout feature: the system compares the current price with 90 days of historical data and labels it as an all-time low, good price, fair price, or overpriced, helping users identify “real discounts.” Price data comes from the third-party service Keepa, and the tracking list is stored locally in the browser; the backend receives product identifiers rather than user identities.

Pricing, Integrations, and Security

The page does not disclose any pricing model, plans, or payment methods, nor does it clearly state whether there is a free version or trial. In terms of integrations, it currently supports only Amazon, with more retailers still planned. Its privacy design is relatively restrained: no registration is required, and a random anonymous ID is generated on installation for rate limiting; when a purchase is confirmed, only the savings amount is uploaded for global statistics. On compliance, the text does not provide information about GDPR, SOC 2, ISO, or similar certifications, and there is no mention of team permissions, audit logs, APIs, or developer support.

Pros and Cons

Its strengths are that it is very easy to get started with, low-interruption, stores the tracking list locally, and uses historical average prices to judge whether a deal is worthwhile, making it more informative than a simple price-drop alert. The downsides are also clear: refreshing once per day is not real-time monitoring, so short-lived promotions may be missed; pricing depends on third-party data, which the official text also notes may be delayed or inaccurate; it currently supports only Amazon, and as an individual project, the service may stop at any time.

Who It’s For and Access from China

It is suitable for individual users who often shop overseas or use Amazon, especially those willing to wait for price drops and who do not want to sign up for a more complex price-comparison service. It is not suitable for organizations that need team collaboration, permission management, purchase approval workflows, or enterprise compliance. The text does not specify access conditions from China; because it depends on Amazon, the Chrome Web Store, and overseas services, the actual experience may be affected by the network environment. Alternatives include Keepa, CamelCamelCamel, and Honey, while domestic price-comparison options in China include Manmanbuy and SMZDM.
