I've an idea for a friend recommendation strategy. As my product is an educational title for children, word-of-mouth from parents will be a key means to generate publicity. I'd like to augment this by providing every customer with a voucher that they can pass on to friends & family to get a discount. However, I would like the voucher to only work with 2 customers. These in turn would get a voucher to pass on to 2 friends, who when they bought would get a voucher. This way each voucher would be accompanied by a personal recommendation rather than being a generic voucher.
So, is there any possibility of this being added, with auto-generating vouchers that can be included in the purchase email via a control code [%voucher1]? Ore would that just mean too many vouchers for the system to cope with?
