# Types of bundles

**Offer Types & Combinations**

  In this article, we'll walk through every offer type the app supports, and how they can be combined to build the exact promotion
  you're after.
  
  **Quantity Offers (Same Product)**

  Choose the product you want to discount, then set a per-unit discount that applies as the customer adds more of that same item. This
  discount can be a percentage off or a fixed amount off.

  **Mix and Match**

  Select several products to include in the offer, and set a discount that applies based on their combined price — again, either a
  percentage or a fixed amount. With Mix and Match, the customer chooses which eligible products to include, effectively building
  their own version of the bundle.

  **Product Bundle**

  A Product Bundle is a fixed, predefined set of products sold together as one offer. Unlike Mix and Match, the contents are locked in
  when you create the bundle — customers can't substitute products, and you can't add products outside that original selection later.

  **Buy X Get Y**

  You can build a Buy X Get Y offer using either the Mix and Match or Quantity Offer type as your base.

  Set up the first tier with 2 products, and apply one of the following:
* A 50% discount (percentage-based), or
* A fixed discount equal to the price of 1 product (fixed-amount based) — in effect, "2 for the price of 1"

  For each additional tier, double the number of products from the tier before it, keeping the same discount logic:
* Fixed discount: the discount amount stays equal to one product's original price
* Percentage discount: stays at 50%

**Free gift**

3. Set your second tier as 100% discount. 

In case you are using more than 2 tiers, make sure to select last tier as full discounted product (product will be one of products you have assigned for the offer)
