This is an example of a Course Product Package - open me for more details on setup and usage.
The simpler version of the Course Product is generally OK where you expect your visitors to select discrete item(s) from the list of available items; they can even add several instances of the Product with a different item selected each time and often this is the best approach. But if, for example, you are running a three day coaching camp where each day might have a different price and a different level of Inventory, a Product Package might be the way to go.
This is even more relevant when you are looking to sell a mixed package of Products but want to make it quick and easy for visitors, e.g. attend one or more of a range of coaching sessions, optionally purchase some merchandise or equipment, attend a formal dinner afterwards.
Examples might include Specialist Coaching, 1-2-1s, Summer Camps, and Coach Education. You would most likely only look to collect data to identify the person for whom the Product has been purchased, but as with the Simple Course Product, you might also need to collect medical and emergency contact data.
