CupomLouco — Coupons & Comparator by CupomLouco

CupomLouco — coupons, deals, and a real-time price comparison tool.

Search for any product and compare offers side-by-side from stores in Brazil and around the world: the cheapest are highlighted in green and the most expensive in red, always showing the difference in percentage and currency (R$). Exact models appear first, with similar items listed separately—so you never compare unlike products.

Features:
- 🔍 Multi-store comparison tool (Amazon, Mercado Livre, Shopee, Magalu, KaBuM!, AliExpress, and more) with filters for store, category, country, and currency (BRL, USD, EUR, and others)
- 🎟 Verified coupons tab, featuring "one-click copy" and "Use" buttons
- 📈 Price history (weekly/monthly) with charts in the full comparison view
- 🔔 Price drop alerts via email + deal subscriptions via email/WhatsApp
- 💰 Discreet bar on store pages showing the detected price and available coupons for that specific store
- 🌎 3 languages (PT/EN/ES), "real data only" mode, and anti-fraud/anti-phishing protections
