VAT
As a small business under Section 19 UStG, we do not charge German value-added tax. Commission income from affiliate programs is invoiced without German VAT; tax may still be handled by the operator of the respective program in its own jurisdiction.
Advertising and affiliate links
SupplementPrices is a participant in the Amazon Services LLC Associates Program and the corresponding programs of the other Amazon marketplaces. Product links on this site carry an affiliate tag, and we earn a commission from qualifying purchases at no additional cost to you. These links are marked as advertising and are set as rel="sponsored nofollow". The ranking itself is computed from prices and label data alone and is never sold, sponsored or otherwise paid for.
Consumer dispute resolution
We are not willing or obliged to participate in dispute resolution proceedings before a consumer arbitration board (Verbraucherschlichtungsstelle). The former European Commission online dispute resolution platform was discontinued on July 20, 2025.
Liability for content
The contents of this website have been created with the greatest possible care. As service providers, we are responsible for our own content on these pages in accordance with Section 7(1) DDG under general laws. According to Sections 8 to 10 DDG, however, we are not obligated to monitor transmitted or stored third-party information or to investigate circumstances that indicate illegal activity.
Prices, product titles, package sizes and label data are third-party information retrieved automatically from the Amazon Product Advertising API and from public product pages. They can be incomplete, outdated or wrong at the source, and we do not adopt them as our own statements. Obligations to remove or block the use of information under general laws remain unaffected; liability in this respect is only possible from the point in time at which a concrete infringement of the law becomes known. If we become aware of any such infringements, we will remove the relevant content immediately.
Liability for links
Our website contains links to external websites of third parties, over whose contents we have no influence. Therefore, we cannot assume any liability for these external contents. The respective provider or operator of the linked pages is always responsible for their content. The linked pages were checked for possible legal violations at the time of linking. Illegal content was not recognisable at the time of linking. A permanent content control of the linked pages is, however, unreasonable without concrete evidence of a legal infringement. Should any such infringement come to our knowledge, we will remove such links immediately.
Copyright
The content and works created by the site operators on these pages — including the category model, the normalisation methodology, the computed price metrics and the compiled database behind them — are subject to German copyright law and to the sui generis database right under Sections 87a et seq. UrhG. Duplication, processing, distribution, systematic extraction and any form of commercialisation of such material beyond the scope of the copyright law require the prior written consent of its respective author or creator. Downloads and copies of this site are only permitted for private, non-commercial use.
Insofar as the content on this site was not created by the operator, the copyrights of third parties are respected. In particular, content from third parties is marked as such. Amazon, the Amazon logo and related marks are trademarks of Amazon.com, Inc. or its affiliates; product titles, images and descriptions originate from the respective manufacturers and are used under the terms of the Amazon Associates and Product Advertising API agreements. Should you nevertheless become aware of a copyright infringement, please let us know. If we become aware of any infringements, we will remove such content immediately.
Applicable law
German law applies to this website and to its operator. Where the law permits a place of jurisdiction to be agreed, it is Göttingen, Germany. Mandatory consumer protections of your country of residence remain unaffected.
