The Bundle offer type will offer customers a discount when they buy certain items together.
Step 1: Name your offer
Each offer requires a Name before it can be saved. You can also choose to have your offer Enabled or Disabled on the storefront.
Step 2: Set up the Bundle offer
Choose bundle items to discount
Add the first bundle item you want to include in your offer. If you choose a single product, the customer will be required to purchase multiples of that product in order to receive the discount. If you choose multiple products or a collection, the customer will be able to select any combination of those products to receive the discount.
Click add another item to specify another product (or products) to be included in the bundle.
If you have selected specific products for your Bundle offer, customers will have the option to add all Bundle products to the cart from the product page.
Choose discount
Select whether the discount will be applied as a percentage or fixed dollar amount.
Discount percentage: Set a percentage-based discount for the offer.
Example: Get 15% off when you buy the Alaska Creamer and the Alaska Cup together.
Discount amount: Set a dollar-based discount for the offer.
Example: Get $10 off when you buy the Alaska Creamer and the Alaska Cup together.
New price: Set a new price discount for the offer.
Example: Buy the Alaska Creamer and the Alaska Cup together for a new price of $39.99.
You can also choose whether to display an upsell popup with sale products on the cart page. 
Step 3: Edit offer messages
The Initial message will show in your notification banner, the bundle widget on the product page, and in the upsell popup on the cart page. Use this message to advertise the details of your offer.
The Success message will show on the cart page when the bundle products have been added to the cart.
