How the comparison works
Núkleo compares the price and availability of products across sellers operating in Italy. Here, in plain terms, is how we do it and where the limits are.
Coverage is not exhaustive
The comparison does not necessarily include every seller on the market. We show sellers for whom we have reliable, authorised data. A shop's absence is not a judgement on that shop.
Where the data comes from
Prices and availability come from authorised merchant feeds, affiliate programs, or verified manual entry. We do not scrape third-party sites and we do not copy others' descriptions, images or reviews.
Every price has a date
Each offer shows the date the price was recorded. Prices are indicative and can change: always verify the final price, shipping and conditions on the seller's site before buying.
How results are ranked
Ranking is organic: available offers first, then by ascending total price when shipping is known (otherwise by product price), then by most recent update. Affiliate commission NEVER influences the order.
Affiliate vs external links
Some links are affiliate links: if you buy through one, Núkleo may earn a commission, which does NOT increase the price you pay. Where we have no agreement with the seller, the link is a plain external link and we earn nothing. We label this clearly.
Possible errors
Despite checks, a price or availability can be out of date. Stale offers are de-emphasised and flagged 'price to verify'. Tell us about any errors and we'll fix them.
Not medical advice
The comparison is about commercial features and availability. It does not provide diagnosis, prescriptions or therapeutic advice. For health decisions, consult a doctor or healthcare professional.
