+| How is the `product.relative_discount` variable calculated? |  `relative_discount` returns the localized discount percentage of a given package compared to the most expensive package per period that's offered on your paywall. For example, if you're displaying a monthly package that is $10/month, and a yearly package that is $80/year (or $6.67/month), the relative discount for the annual package is 67%. Because of this, we recommend only using this variable within packages that are NOT the most expensive package per period, as the most expensive package will have a null value returned, since its relative discount is null. |

+#### Paywalls on iPad
+When using `presentPaywallIfNeeded` to display a paywall on iPad, we'll automatically show a paywall in a modal that is roughly iPhone sized. If instead you prefer to show a paywall that is full screen on iPad, you can use the `PaywallView` or `PaywallViewController` methods instead.
