At which point does giving discount to customers devalue a business?

[Min George]

It is possible that customers rate your business less because you offer so many discounts. Buy discounts can also encourage customers to patronize.

How do you give discounts such that you don't devalue your business in the process?

 

[King Belieal]

When discounts are too frequent that the customers get used to buying at discounted prices, it totally devalues a business.
