SpellBook Sealed Deal Check BETA

THIS EXTENSION IS FOR BETA TESTING. Check sealed Magic box EV on TCGplayer, eBay, stores, and Facebook Marketplace.

SpellBook Sealed Deal Check helps Magic buyers evaluate sealed boxes without leaving the page they are shopping on. When you click the extension on a supported page, it scans the visible product title and price, resolves the sealed product against SpellBook Finance, and adds an inline badge with EV ratio, crack value, page price, cheapest known store when available, notable card values, and a link to the full SpellBook Finance box breakdown. Supported beta surfaces include TCGplayer sealed product pages, eBay item pages, supported store product pages and product grids, and Facebook Marketplace item pages visible to the user. The extension only scans the current tab after the user clicks the extension icon. It does not read account credentials, messages, payment information, cookies, or full browsing history.
