# Offer Types

## Understanding Checkout Extension Offer Types

Before diving into the detailed setup guides, it's helpful to understand the three core offer types supported by Checkout Extensions: **Preset**, **Preset List**, and **BOGO**.

These offer types can be used in both **Auto Add Gift** and **Manual Selection** modes, but they behave differently depending on which mode you choose.

***

### Preset

A Preset offer contains a fixed set of products and quantities defined by the merchant.

For example:

* Water Bottle × 1
* Tote Bag × 2

Whenever the offer is triggered, these exact products and quantities are used.

<details>

<summary>Behavior in Auto Add Gift</summary>

The products are automatically added to the customer's cart when the offer conditions are met.

**Example:**\
Buy any Sneakers → Automatically receive 1 Water Bottle.

</details>

<details>

<summary>Behavior in Manual selection</summary>

The customer is shown the products and can choose whether to add them to their cart.

Unlike Auto Add Gift, Manual Selection also supports:

* Free products
* Percentage discounts
* Fixed-price offers
* Full-price upsells

**Example:**\
Buy any Sneakers → Add a Water Bottle at 50% off.

</details>

***

### Preset List

A Preset List allows merchants to offer a collection of products rather than a fixed set.

For example:

* Water Bottle
* Tote Bag
* Coffee Mug
* Keychain

<details>

<summary>Behavior in Auto Add Gift</summary>

Products from the list are automatically added to the cart based on the configuration.

You can choose:

* Fixed quantities
* Dynamic quantities derived from cart conditions

{% hint style="info" %}
Buy 3 qualifying products → Automatically receive:

* Water Bottle × 1
* Tote Bag × 1
  {% endhint %}

</details>

<details>

<summary>Behavior in Manual selection</summary>

The customer chooses products from the list.

You can control:

* How many products they can select
* Whether products are free or discounted
* Whether the selection limit scales dynamically

{% hint style="info" %}
Buy 3 qualifying products → Choose 1 free gift from the list.

Buy 6 qualifying products → Choose 2 free gifts from the list.
{% endhint %}

</details>

***

### BOGO

BOGO (Buy One Get One) creates offers where rewards are derived from products already present in the cart.

Instead of choosing a predefined gift, the offer is calculated using qualifying products.

<details>

<summary>Behavior in Auto add gift</summary>

Rewards are automatically added to the cart.

Supported modes include:

**Match Cart Line Quantity**

Mirror the quantity purchased.

**Example:**\
Buy 2 Sneakers → Receive 2 Sneakers for free.

**Fixed Quantity**

Limit the reward quantity regardless of how many products are purchased.

**Example:**\
Buy 10 Sneakers → Receive 1 free Sneaker.

**Dynamic Quantity**

Calculate rewards using a formula.

**Example:**\
For every 3 qualifying items purchased, receive 1 free item.

</details>

<details>

<summary>Behavior in manual selection</summary>

The same BOGO calculations apply, but customers choose whether to add the rewards themselves.

This provides a more interactive experience and allows customers to decide which qualifying rewards they want to claim.

**Example:**\
Buy 6 qualifying items → Eligible for 2 free rewards. The customer chooses which rewards to add.

</details>

### At a Glance

| Offer Type  | Auto Add Gift                                                    | Manual Selection                                               |
| ----------- | ---------------------------------------------------------------- | -------------------------------------------------------------- |
| Preset      | Automatically adds predefined products                           | Customer chooses whether to add predefined products            |
| Preset List | Automatically adds products from a configured list               | Customer chooses products from a list                          |
| BOGO        | Automatically calculates and adds rewards based on cart contents | Calculates rewards but customer chooses which rewards to claim |

In general, **Auto Add Gift** is best when you want a seamless, hands-off customer experience, while **Manual Selection** is best when you want to give customers choice, run upsells, or offer discounted products in addition to free gifts.
