# A different percent off each collection, in one Shopify code

A Shopify discount has one value, so 20% off your Summer collection and 10% off Accessories would normally be two codes. With [OneCode: Stackable Discounts](https://apps.shopify.com/rm-combo-discounts), you add one product discount per collection to a single code, each with its own percentage. The customer enters one code, and each item gets the percentage for its collection.

## Example

The code `SUMMER` gives 20% off the Summer Collection and 10% off Accessories. A customer buys a $50 shirt from Summer and a $20 tote from Accessories:

- The shirt is $10 off, so it costs $40.
- The tote is $2 off, so it costs $18.

The items come to $58, and with $8 shipping the customer pays $66.

## Set it up

1. In OneCode, click **Create discount**, choose **Discount code** and enter `SUMMER`.
2. Click **Add Discount Type**. Leave it as a **Product Discount** with **Percentage**, and enter `20`. Set **Target** to **Specific Collections**, then search or click **Browse** and pick the Summer Collection.
3. Click **Add Discount Type** again. Enter `10`, set **Target** to **Specific Collections** and pick Accessories.
4. Click **Save discount**.

Add as many collections as you need, each as its own discount type. To give several collections the same percentage, pick them all in one discount type.

## When a product is in both collections

It gets the bigger discount, not both. A shirt in Summer and Accessories gets 20% off, not 30%. Each item gets one product discount from the code: the one that saves the most.

## A different percent for everything else

To give 20% off Summer and 10% off everything else, set the second discount type's **Target** to **All Products** instead of picking Accessories. Summer items qualify for both and get the better 20%. Everything else gets 10%.

## Add free shipping

Click **Add Discount Type**, set **Discount Type** to **Shipping Discount** and keep **Free Shipping**. The same code then covers both collection discounts and shipping. See [20% off and free shipping in one code](/guides/20-percent-off-and-free-shipping.md).
