In our articles we use product images as well as direct links to online stores, which are specially marked. This means: If someone clicks on one of these links in the article and buys the product in the online store, we in some cases get a commission from the purchase price.
We cooperate with partners and affiliate networks like Amazon. These networks are the link between us and the online stores whose products we integrate into some article. Via the affiliate links, the user is redirected to the online store and can directly shop the desired product there.
