I want to lower the price to some specific consumers for open promotion. I'm thinking of using promo code or email check.
For example,
if(*coupon code entered*)
new_subscription_price = original_subsciption_price * 0.5;
or,
if(*email is end with .edu*) //unknown@unknown.edu
new_subscription_price = original_subsciption_price * 0.5;
Is there any possible way to change price only for specific consumer? I use flutter, both google and ios platform. If it is possible, how it works?
