Yeah, I got a reply as well. Looks like it's only valid for iOS, Android and Kindle (they want Apple, Google and Amazon receipts). Also, it can only be used for table purchases, ball purchases and future season pass credit, I'm guessing on the same platform.
Oh well, I'm not getting it if that's the case. If I could've applied it towards the PC version and added the PS3 purchases to that, I would do it (on both PS3 and iOS). But as it is, I don't see the benefit.
