A lot of buyers say they stay loyal to a brand simply because it always does what it says it will do. If a shop promises fast delivery and delivers fast every time, people start to relax and stop checking other options. Trust seems to grow slowly through repeated small actions rather than one big gesture. Still, keeping every single promise without fail is hard, especially as a business grows bigger and takes on more customers at once. Is keeping promises enough to build lasting trust, or does a brand need more than that?
