This seems to suggest they won't recommend a product if they can't make an affiliate deal off of it, which is not the case. Yes, they make money through these links, but I've not seen a case of them not referring to a good product because it is not available on a store they have an affiliate deal with. And if the product is their chosen product and no affiliate deal is there, they link to the brand store or other retailer.
