I'm an iOS dev. We've had multiple rejections of our apps because we added a "promo code" button to the paywall, which literally displayed the Apple sanctioned code redemption sheet from StoreKit.

We get through it via escalation, but we always expect a week or two of update downtime with every bug fix release for something stupid like this.
