Another novelty this week!
We know that consumers trust consumers much more than merchants themselves!
So if a merchant tells you: "this product is the best", few of you will be convinced.
On the other hand, if another customer tells you "I tested it, it is really the best!", Then the doubt will be removed and there will be a phenomenal queue at the checkout!
This is called social proof. This principle has been applied since the beginning of time and it is very human :-)
