If a returned product is a master product, the customer is entitled to choose from any variant. If the product is an option product, the customer is entitled to choose any value for each option. Since the promotions engine does not touch the value of the product option line items, it is the responsibility of custom code to set option prices.
If the promotion is rule based, then this method will return an empty list. A ProductSearchModel should be used to return the bonus products the customer may choose from instead. See ProductSearchModel.PROMOTION_PRODUCT_TYPE_BONUS and ProductSearchModel.setPromotionID(String)
