Businesses are established with the aim of solving a problem, rendering a service and making profits (as much as possible). No one ventures into business to lose the capital invested in it.
It's respect for ethics that makes a business owner prioritize trust over profit.
There are so many scam online vendors, countless stories of how they sell ridiculous things and block their customers. I don't understand how they can not stick to selling exactly what they post, make their customers happy and get referrals too.
