Thanks for your reply. I did read your explanation, and I did create an in-app purchase test user. I insured I was not logged into any Apple Web site. On the device, in Setup I configured the Store info to use the test user. I entered a valid credit card, address, etc., and was able to log into the iTunes store. Should I not enter credit card info and leave Apple's address? Thanks in advance for your suggestions.

It's not easy to do this. But you can use the work around i explained in this blog post.

http://blog.mugunthkumar.com/coding/iphone-tutori...

Release a minor update to your "paid" app and collect all Device IDs in your server. Use MKStoreKit v2.0 and setup your server with the sql scripts given. Set the ownServer property to your server location. MKStorekit will automatically ping your server to check your device id tables to check if the user has already purchased the paid app and enables the in-app for free.

Or come back to my blog by this weekend. I'm actually writing a tutorial on this right now

Just wonder if any developer is at the similar stage. I'm planning to make a transition an existing paid app to free version with "In App Purchase". For example, the original one is version 1.0 and it's a paid app. After updating to version 2.0, it will be free + "In App Purchase". What I concerned is that will the original version 1.0 buyers be charged again because this kind of transition?

you should create a test user account, signout of the appstore on your test device, use the test user account to test the in-app purchases. This is explained in Step 4 of \"Preparing the iTunes Connect\" section.

Thanks,
MK

Thanks for the very helpful tutorial. The code is easy to implement and use. I'm having an issue I haven't seen mentioned. When I try to buy a product in the sandbox, I get the normal buy verification alert with the correct product ID and price. When I press BUY, I get another alert saying that "Your account info has changed. Tap Continue to sign in, then review and confirm the changes. [Environment: Sandbox]" If you press Cancel, control is returned to my code and I can press another selection or exit. If I press Continue, my code exits (return code 0, it is not a "crash"), but the store loops asking for my password, then presenting the "account info has changed" alert. Any ideas?

Lets say your identifier for "A" is "com.yourcompanyname.A"

So for x, y and z you need to create three more products in itunes account for in app purchase with following identifiers:
com.yourcompanyname.A.x, com.yourcompanyname.A.y and com.yourcompanyname.A.z. And set the pricing for each sub product what you want.
