Deal Score is a 0–100 assessment of the current price against confirmed recent and longer-term price history for the same listing and marketplace. It combines price hike, all-time low, average price and historical range checks. Sale mode also compares the previous sale price when recorded. Normal weights are 40%, 25%, 20% and 15%; sale weights are 40% integrity, 15% last sale, 20% all-time low, 15% average and 10% range. Unavailable checks redistribute their weight proportionally. MRP, advertised discount, ratings, popularity and sponsored placement do not add score points.
Each check applies its own history requirements. A new all-time low earns 100; matching the recorded low earns 95. Average and range use the same eligible historical window, and a flat range is unavailable. Missing checks add no points. Confidence describes the available evidence and is separate from the score. Deal Score is neither a product-quality review nor a prediction of the next price.
