DealStack

DealStack is a mobile + browser-extension app (traditional + AI) that calculates the real, final price before you buy by automatically stacking eligible coupons, loyalty rewards, credit-card offers, and store promos. Users link loyalty accounts and optionally connect email/receipts to detect available offers; the app then recommends where to buy (online or nearby) with the best net price after rewards. The AI layer focuses on messy promo rules: exclusions, minimums, category limits, and “one-per-order” constraints, turning them into a clear “you’ll pay $X” summary. It also tracks expiring points and suggests the best time to redeem vs save. Brutal truth: this only works if you can reliably ingest offers and keep rules updated—so the MVP should start with a narrow set of retailers and expand only when accuracy stays high.
