Glass It checks the price of products you pick every day and notifies you by email or push when it moves, keeping a visual history and alerting when something comes back in stock. It works across whichever retailers you choose, through extensions for Chrome, Firefox, Safari and Edge, iOS and Android apps and a web dashboard.
Price history is what makes it a consumer protection tool rather than a coupon site. A retailer marking an item down from a price it never actually sold at is a long-standing tactic, particularly around sale events, and a chart showing what the thing has genuinely cost over months is the only way to tell a real discount from a manufactured one.
Glass It LLC operates from Florida with free and paid tiers, and the free plan tracks up to three items a month. Exact paid pricing is not published and the site’s explanation of costs is vague. Three items is a demonstration rather than a shopping habit, price tracking depends on retailers not blocking the checks, and browser extensions with access to shopping pages see your browsing on those sites.
