Does the KY1081 massager's wholesale customer have a price protection policy? How is the quantity discount calculated?

A 5% discount is offered for orders of 500 units or more, a 10% discount for orders of 1,000 units or more with free customized packaging, and exclusive agency prices can be negotiated for orders of 5,000 units or more. New customers can apply for a trial order of 50 units at the wholesale price for their first order without any minimum order quantity pressure.
