Dealing with In-App Purchase

  1. Can we upload products in bulk at iTunes, like all product in json file and just upload at iTunes for review?.
  2. Do In-App Purchase have discount mechanism?
  3. What will happen if we don't go for In-App Purchases, cause it have some limitations. Might it would be rejected by Apple? How we will defend it? Please suggest some way.
  4. Can we set unique price for different states or provinces across the world?
