If you are looking for a specific product, either go directly to the address bar of your browser and enter the URL (which is the safest way), or you can search for the best price through one of the popular search engines.
In general, fake shops have a rather poor search engine ranking, so you have to go down quite a bit in the results list to get straight to those sites. However, there are countless affiliate sites that attract users with product reviews.
The one then clicks on it is quite understandable, if you get besides the best price also a more or less detailed product test included. Unfortunately, it is often the case that this is the first step into the unknown. For more and more often, the operators of such sites do not even sit in the EU, but camouflage themselves with the local language.
The product tests you find there are very often stolen by really trusted portals to fake seriousness. And the links with which you come to the product then point to a well-known online shop, which was again faked.
