# Spend more, save more tiers in one Shopify automatic discount

In Shopify's own discounts, each tier is a separate discount. With [OneCode: Stackable Discounts](https://apps.shopify.com/rm-combo-discounts), every tier goes in one automatic discount, or one code. For 20% off, rising to 30% off from $300, add a 20% product discount with no condition and a 30% product discount that needs a cart subtotal of at least $300. Customers get the best tier they reach. The tiers don't add up, so a $320 cart gets 30% off, not 50%.

## What the customer gets

- A $250 cart gets 20% off, $50 saved. The items cost $200.
- A $320 cart gets 30% off, $96 saved. The items cost $224.

Shipping is charged as normal, $8 in these examples.

## Set it up

1. In OneCode, click **Create discount** and choose **Automatic discount**. Enter a **Title** such as `Spend more, save more`. Customers see the title next to the discounted items in their cart and at checkout. Choose **Discount code** instead if customers should type a code.
2. Click **Add Discount Type**. Leave it as a **Product Discount** on **All Products**, and enter `20` in **Percentage**. Add no condition.
3. Click **Add Discount Type** again and enter `30`. Under its **Per-Discount Conditions**, click **Add Condition**. Set **Field** to **Cart Subtotal**, **Operator** to **Greater than or equal to** and **Value** to `300`.
4. Click **Save discount**.

Add more tiers the same way, for example 40% at $500. To run the tiers on one collection, set the same **Target** on every tier.

## The $300 is measured before discounts

**Cart Subtotal** is the cart's value before any discount comes off. A $320 cart reaches the 30% tier even though 20% off would bring it to $256. Tiers can't be measured after the discount, so if you want customers to spend more before they reach 30%, set a higher threshold.

Cart Subtotal counts everything in the cart. If your tiers cover one collection and only that collection's items should count toward the $300, use **Group Subtotal** instead. It counts only the items the discount type targets.

## Tiers on the order total instead

To show one discount on the order rather than a discount on each item, use **Order Discount** types with the same thresholds. Only the biggest order discount that qualifies is used. With $10 off at $100 and $25 off at $200, a $250 cart gets $25 off, not $35.

## Add free shipping

Click **Add Discount Type**, set **Discount Type** to **Shipping Discount** and keep **Free Shipping**. Give it its own **Cart Subtotal** condition if free shipping should start at a different amount. See [20% off and free shipping](/guides/20-percent-off-and-free-shipping.md).

For tiers based on how many items are in the cart, such as "buy 2 save 10%, buy 3 save 15%", see [buy more, save more](/guides/buy-more-save-more.md).
