Methodology.

ComparEuro collects prices directly from the product pages of each country's official Amazon store: Amazon.fr (France), Amazon.de (Germany) and Amazon.es (Spain).

Only products sold and shipped by Amazon itself or by official brands are included. Third-party sellers on the Amazon marketplace are not taken into account, to guarantee price reliability and the presence of a manufacturer warranty.

The price shown on ComparEuro is always the total price delivered to France, meaning:

• Product price (tax included) as shown on the relevant country's Amazon site
• Standard shipping cost to mainland France (estimated or actual, depending on availability)

Customs fees are not included in our calculation. As a member of the European Union, purchases between member states are not subject to customs duties, but VAT differences may apply in some cases. We recommend checking the final amount at checkout.

Prices are checked and updated regularly. The last update date is shown on each product page. Amazon prices can change several times a day, especially during promotional periods (Prime Day, Black Friday, sales, etc.).

Important: Always check the price shown on the Amazon site at the time of your purchase. ComparEuro cannot guarantee that the price shown on our site exactly matches the actual price at the time of your order.

Products featured on ComparEuro are manually selected based on their popularity, identified potential savings, and availability across the three covered countries. We favor products where the price gap between countries is significant and verifiable.

ComparEuro participates in the Amazon EU Associates Program. Links to Amazon on this site are affiliate links: if you buy a product through one of these links, ComparEuro earns a commission on the sale, at no extra cost to you. This commission funds the development and maintenance of the site.
