Package / Combination Discounts

Do you need to created a discount dependent on many different items sold as a package deal?

Create a discount, with all value taken off a single item, where the requirement of other items purchased has been met
Create multiple discounts, where each items discount is applied, dependent on the other items purchased
Create a hidden category to scope your discount
Create a recipe

eg get 30% off 1 banana if you buy 1 apple and 1 orange
Decide which item should get the primary discount (Value and scope of offer) eg Banana
Limit quantity of discounted items, per minimum quantity reference items. eg 1 Banana for every reference item set.
Decide which reference items are required to achieve the combination. (eg 1 Apple and 1 Orange)
Set min quantity items to 1, as it's 1 apple and 1 orange required

eg get 10% off banana, apple and oranges, if you buy at least 1 from each group.
Create multiple discounts in the discount manager, 1 for each fruit
Take the same approach as the previous single discount approach, but alternate the fruits between the scope and conditions.

The use of a hidden category can be used to simplify the offer management.
However, using this approach does not require a customer to purchase something from each and every sub category.

A recipe is not really a discounting method, but may be used to create a package of products at a reduced price.
A recipe does not indicate what the RRP of the component products was, so the customer is unaware if they are getting a discount or not.

The best discount wins. (if another discount makes a better offer for any given line, then that other discount applies.
Each line if your basket is for a single product only
Each line in your basket can win a different discount. (maybe 10% off apples, 15% off oranges etc)
A single discount can be applied to multiple lines, you might purchase different sorts of apples, and each of those lines gets the apples discount.
A merchant may want to create a bundled discount, but the only way to do this is to either apply all the benefits to a single product on condition of the other items being purchased, or to create multiple discounts that cross reference each other and hope there is no other discount that offers a better deal for an individual product.
Discounted items can still be a reference item for another discount. So you hence you can create different discount rules for each of the fruit types, and even as each discount applies to each fruit type, that line item can still be used as the reference item for the next discount.
