How DON IT works

01 · Where prices come from

Product feeds from our retail and resale partners (Awin, Tradedoubler, CJ, Rakuten, impact.com, eBay Partner Network), refreshed daily and converted at ECB reference rates. We don't scrape marketplaces.

02 · How we know it's the same item

Barcode (GTIN/EAN) first, then brand + manufacturer part number, then fashion-specific image and text similarity. Every result carries a confidence level.

03 · How the verdict is calculated

We compare your price with new prices across shops and pre-loved prices from the last 60 days. Low: in the cheapest quarter of retail or close to the resale price. High: above the most expensive quarter of retail while resale sells under 60% of it.

04 · How we make money

Commission when you buy through a partner link. Commission never affects ranking — results are ordered by price. Partners can't pay for placement.
