It doesn't look like you can generate promo codes for IAP via Apple (or am I wrong?).

I'm attempting to use the model where people can play the initial game for free, and then expand it with new areas via IAP. I'd like to give my testers and reviewers access to all the IAP content.

Without promo codes, how should I go about it? I guess I could just give them the money to buy the content themselves, but would rather do it in some way that was free. :)

Thanks!

this is not possible from itunes connect. but you can have work around if you have a server to send back a preset command to trigger a free upgrade

That makes sense! Now, just gotta find some good "redeem coupon via network server" sample code. ;)
