How we rank offers
Simple, public rules — the same for every shop.
How are a product’s offers ranked?
Available offers with declared shipping first, by total cost (price + shipping); then offers with unknown shipping, by price; out-of-stock last. Ties go to the most recently checked offer.
Are there paid positions?
No. If there ever are, they will be labelled “Sponsored” and the rules published here.
What does “lowest total cost” mean?
The lowest price + shipping among offers verified by Purceas CSS — not the whole market.
How do you know it is the same product?
By EAN/GTIN or brand + manufacturer code, keeping size, colour, capacity, condition and multipacks apart. Similar titles never merge products.
Offers not confirmed by the shop for 7 days expire; those older than 3 days are labelled. In search we rank by text relevance, then number of shops, then lowest price.
