yes, i am always suprised that such a tool does not exist everywhere (at least the modern western world...). not every shop is in there and rarely I buy from elsewhere... but even just checking specs of any kind of "hardware" (geizhals has also home appliances, ...), or seeing what is available with certain specs, geizhals is a godsend.

and it mostly still has that "old-web"-style :-)

originally geizhals.at, geizhals.eu for a wider market. skinflint.co.uk and cenowarka.pl exist as well

In the Netherlands we typically use https://tweakers.net/.
