I think your idea for students is great. You have a captive audience!!! So I’m guessing you may be a student. Think what would entice you. A free meal? Magazine subscription, Hair cut, Cinema tickets, itunes vouchers?
I am in the process of starting a hair cut deal aimed at women for a bingo operator. This is being trialed over a small localised. If successful I aim to take it further. The issue of fraud protection is a tricky one and I am going to ask all users to email me with sign up date and time and user name. Once this is recieved and verifiyed I’ll send out a voucher. Also informing the salon. This is labour intensive at the moment and would not be practicle on a larger scale. Its a learning curve!!
