## AppstockAdInfo

The `AppstockAdInfo` class serves as a container for metadata related to bidding, such as the bid price.

| Property | Type       | Description |
|----------|------------|-------------|
| `price`  | `NSNumber?` |  Bid price expressed as CPM although the actual transaction is for a unit impression only. Note that while the type indicates float, integer math is highly recommended when handling currencies. |
