**Troubleshooting:** If you do not get back your product(s) then there's a good chance that something in your iTunes Connect or Xcode is not properly configured. Take a look at this [StackOverflow Answer](http://stackoverflow.com/a/11707704/293280) to determine what might be the issue(s).
+#### Introductory Price
+
+If an `SKProduct` returned by the store contains an `SKProductDiscount` it'll be described inside `introductoryPrice` as follows:
+
+| Field | Type | Description |
+| ------------------ | ------- | --------------------------------------------------- |
+| price | number | The price as a number |
+| numberOfPeriods | number | Number of periods the product discount is available |
+| paymentMode | string | The payment mode for this product discount |
+| subscriptionPeriod | object | Defines the period for the product discount |
+
+Where `paymentMode` can be any of `['freeTrial', 'payAsYouGo', 'payUpFront', 'unavailable']`.
+
+And `subscriptionPeriod` contains:
+
+| Field | Type | Description |
+| ------------------ | ------- | ----------------------------------------------------------------- |
+| unit | string | The number of units per subscription period |
+| numberOfUnits | number | The increment of time that a subscription period is specified in. |
+
+Where `numberOfUnits` can be any of `['day', 'week', 'month', 'year', 'unavailable']`;
+
+If the product has no `SKProductDiscount` associated, `introductoryPrice` will be set to `null`.
+
+**Note:** Introductory Price is only available in iOS 11.2+, if ran in another version `introductoryPrice` will be set to `null`.
+
