We have an in game store setup and working with both virtual currency and real money transactions. Everything is working fine and we are wondering if there is a secure way to offer a 50% discount on all store items to a select group of users (those who bought the game early on in development). As I understand it, I could create 2 stores and just adjust the prices accordingly, but then a clever user could figure out the store IDs and effectively give themselves and others access to the discounted items. Is there a way to do this securely?
