About App Store promo codes

Question

I have recently released an app on the app store. I would like to allow some to have access to a free version but have some concerns about offering promo codes. My big question is:

How many times can one promo code be used? I guess I'm concerned about a promo code getting into the wrong hands and being distributed...

Thanks! V

Answer 1

A promo code can only be used once. Sometime developers will post a few of them on Twitter or other marketing channels and people can grab one, however if it has already been entered, iTunes will report it as "already used".

Apple has a good summary of how promo codes work.
