CREATE A BUNDLE
If you would like to create a bundled discount, create a specific category in your retail list for the items you want to be in that sale.
After you created your product category with the desired items click "Discounts". Create your discount based on what you need. Select all products within that category.
Set your minimum requirement to the number of items in that bundle - or a minimum purchase amount.
Members will need to meet that requirement to kick in that discount.
It's that easy!
