SprytneOkazje is a platform that monitors Amazon marketplaces across Europe to identify genuine discounts and pricing anomalies. By maintaining a 180-day price history for each product, it filters out misleading promotions where prices are inflated before discounts. Covering ten European Amazon marketplaces, including Poland, Germany, France, and the UK, the system refreshes data every three to fifteen minutes to capture time-sensitive deals. The platform spans categories like electronics, home goods, fashion, and toys, offering price history charts to verify discounts. Custom alerts notify users of price drops or errors, while statistical models flag anomalies exceeding three standard deviations. Users can compare prices across markets, factoring in currency conversion and shipping costs. Operating on an affiliate model, SprytneOkazje provides real-time availability and pricing, helping shoppers find the best cross-border deals within the EU.
