Affiliate Disclosure

As an Amazon Associate I earn from qualifying purchases.

CaffCalc participates in the Amazon EU Associates Programme. Eligible links are labelled as advertisements or paid links near the point where they appear. If you click one of these links and make a qualifying purchase, the site owner may receive a commission at no extra cost to you.

The primary links use the UK tracking tag bendickman-21. Amazon OneLink may redirect an eligible international visitor to a local Amazon store when the associated accounts and matching settings support it. Amazon, not CaffCalc, controls product matching, redirection, availability and checkout.

Affiliate commission doesn’t change CaffCalc calculations or scientific references. Links are optional and aren’t endorsements, medical recommendations or guarantees that a product is suitable for you. Product recipes and caffeine content can change, so check the current manufacturer label before use.

Recommendations are matched to the public page topic, not to private tracker entries or health information. Before adding a named product, we check that its specific Amazon UK listing shows an average rating of at least 4 out of 5. This is a dated editorial check, not a live rating feed, proof of quality or medical endorsement. Ratings may combine variants and can change.

Selections were checked on 24 October 2026 and are due for review by 23 November 2026. Expired selections are removed from the interactive site and rejected by our deployment checks until reviewed again. We don’t reproduce Amazon star ratings, prices, product photographs or customer reviews without an appropriate API arrangement. Check the exact variant, current reviews and pack before buying.

CaffCalc doesn’t display Amazon prices, ratings or stock claims. Any purchase is made directly from Amazon or the relevant marketplace seller and is governed by the retailer’s policies. You can use the calculator and read every article without following an affiliate link.
