I know this might sound like a newbie question but I've been curious about this: I know you can re-download an app you've purchased by clicking the buy button, etc., etc., But does this work if you got the app via a promo code, or even if you got it while it was free but is now back to it's original price? Thanks in advance.
Yes it works. Once you own it, however you got it, it'll always be free. Just as long as the dev hasn't sneakily removed it and then uploaded an identical app.
Ah, ok thanks. That's what I figured but I wanted to be sure. Moderators, you can close this thread now.
