How often do they give their best review score or opinion to a product without an affiliate link? Not every product will have an accessible affiliate link.
Isn’t Amazon commonly used for most affiliate links or has that changed in recent years? Amazon isn’t the cheapest all the time any more. Nor is its customer support the top any more
Also, I've noticed that the list of products reviewed is limited to only those that _have_ Amazon affiliate links. If a product is only available on not-Amazon stores, they don't even get mentioned. Which is a bias in itself.
