Can I add some sort of discount to an app that could be determined by me giving the customer a code of some sort? This would be different from the promo codes, since I don't want to it be free, just different from the original price.
I'm going to guess the answer is no since I haven't seen any replies (or I worded my question poorly).
Another question though: Is it possible to only allow particular people to download an app? For instance, only people with a code would be able to download a given app.
