It is scam like scheme.U should read terms and conditions. 30% discount means after a year ur phone's value would be equal to 30% initial discount when u upgrade to a new model. For example if u purchase note 10 plus for 55000 on 30% discount then u would get only 30% after a year, approximately 25k only ( initial 30% discount). 55000 depreciation would be a huge loss to a customer.
