Methodology
CardPriceLab separates price comparison, card matching, and risk assessment so that a low price is not automatically treated as a good purchase.
1Marketplace data is converted into one consistent listing format.
2Prices, shipping, condition, language, and grading are normalized.
3The matching engine assigns listings to canonical cards with a confidence score.
4Reference prices remain segmented by language, condition, and grading.
5Deal potential and risk are assessed independently.
