Never mark down your product, it has a value, stand by that value.

As a salesperson you never want to devalue your product, it is the price it is, because of the value you stand by. Other alternatives to discounts are offering money back guarantees and longer contracts for lower rates. Additionally, you could exchange cash for, use cases, testimonials or case studies for your sales teams to use. This way you are still keeping the high value of your product but finding creative ways to work with them.
