When our customers buy our Delphin machine, they will not need to buy a same machine for at least another 10 years. Hence, we need to ensure that our company is able to reach out to a large amount of new customers every month. This is why we spent a lot on our roadshows for rental, employees, free gifts and etc. We hope that whoever thinks that Delphin is beneficial can refer their friends and families. As a token of appreciation for help us in saving marketing costs, we will give out SGD200 or SGD300 vouchers for every successful referral. These vouchers can even be accumulated to redeem a Delphin machine or other products such as a variety of household products, baby products, etc.
