I cant see any button for redeem in iPhone, anyway is there anyway I could claimed the purchase with the redeem code?

FYI, Apple has changed their purchase policy. All sales are final, no cancellation or refund, once you hit the BUY button

Hi David, you are kind enough to share the redeem code here

Hope it won't discourage you from sharing more redemption code

cheers mate
