 When clients proceed to the payment step, execute the next method `apply` to charge for bonuses and get the final payment value.
 
+###

+Optional parameters for every single product in the cart can disable some mechanics in the calculation process:
+
+- `"bonusable": false` - forbid to use bonuses for the product;
+- `"discountable": false` - forbid to use discounts for the product;
+- `"rewardable": false` - forbid bonuses reward for the product.
+
+Note: if imported product has a flag which deactivates reward, discounts or bonuses usage, setting a flag to `true` here will not overwrite restrictions from product feed.
+So the main use-case for these parameters: to disable reward, discounts and bonuses usage per product, but not to enable it.
