Belief is the ceiling.
A customer moves through five levels: it looks interesting, it might work, it is worth the money, this is who I am, this is for me. Level three is transactional, and it is the most fragile place a brand can live, because anyone can undercut a price. The test is a single sentence: if you cannot state the transformation without naming the price or the materials, you do not have a belief, you have a discount.
