Same thing here in Czech Republic - you go to a comparison website, check the prizes, availability and reviews of both the think your are looking for and the shops selling them. Then you pick a shop and go to their website (in some cases there is also integration for buying directly via the comparison site).

The main Czech sites:

https://www.heureka.cz/

https://www.zbozi.cz/

It kinda seem like Amazon has been a bit too successful in some parts of the world, to the point people can't imagine alternative online shopping workflows.
