CartBargain

CartBargain helps shoppers stop overpaying by comparing the real, checkout-ready total for a grocery list across local retailers. You build a cart once (by scanning barcodes, importing past receipts, or typing items), then the app estimates the final price including loyalty pricing, digital coupons, and typical taxes/fees. It flags substitutions when an exact SKU isn’t available and shows a “price certainty” score so users know when a deal is reliable versus speculative. The MVP focuses on a handful of major chains per region and a tight set of high-frequency items (staples) to keep data quality high. It’s not magic: some stores block scraping and some prices vary, so the app is transparent about confidence and lets users verify with screenshots or in-app links. Monetization: freemium (limited comparisons) + subscription for unlimited lists and alerts.
