There are many businesses strategies to boost profits, but the few you've highlighted are the ones that matter most. Being polite to consumers, offering discounts to customers, and selling high-quality goods are all crucial in business , especially in stores businesses. If someone wants to succeed in business, they must take on these duties. My personal experience has shown me that to attract customers you play this tree duties.
Too many customers obviously won't increase your profit, and if you're selling things at a loss to them, I don't think that's a good way to attract more customers.
Giving customers discounts doesn't imply you should sell your products so cheaply that you will eventually go out of business; rather, it only means you should offer a small discount in comparison to what others are selling. I firmly feel that this practice helps businesses to attract more clients.
