As an Amazon Associate I earn from qualifying purchases.

The “Check price on Amazon” buttons lead to Amazon.co.uk and carry an associate identifier. If you buy after clicking, Amazon pays me a commission. The price you pay does not change.

Every one of these buttons carries an asterisk (*). Pages that contain them open with a transparency note explaining it: these are paid links. The associate statement appears in the footer of every page. The links go straight to Amazon, with no intermediate page on this site.

What the commission does not influence

  • The selection. A model is included if it is sold in the country concerned and its manufacturer publishes enough data.
  • The order. You sort the tables yourself. No placement is for sale.
  • The data. All values come from manufacturer sources, recorded with their address and the date checked.

Neither manufacturers nor retailers pay to appear on kaffeemetrik.

What you will not find here

  • No live prices, and no prices from retailers other than Amazon. Where available, we show the Amazon price, with the date and time we checked it. It is checked once a day, is not updated in real time and may have changed since. The buttons lead to the current price on Amazon, and the price that counts is the one Amazon shows when you buy. Where the manufacturer publishes a price for the UK, we also show the manufacturer’s RRP, or the price on the manufacturer’s website, with the date we checked it.
  • No customer reviews or star ratings from Amazon.
  • No images from Amazon. Product photos come from the manufacturers and are credited to them.

Which shops are linked

The UK edition links to Amazon.co.uk, the German edition to Amazon.de and the French edition to Amazon.fr. Where no verified product page is on record for a model, the link leads to an Amazon search for that exact model.
