2. From the left navigation, select **Sales** > **Payment Links and Buttons**.
3. Set the maximum number of units a customer can purchase in a single transaction in the **Quantity** field. This setting only applies when you use the **One set price** pricing option, and is useful when you want to limit bulk purchases.

## Variants

Variants let you offer up to three variations per item, such as color, size, or type.

1. In the dashboard, select **Show more options** and turn on **Variants**.
2. Enter a variant name, and list up to 10 options for that variant.
3. Add images and prices for your item’s primary variant.
4. To price each option individually, select **Add price per variant**.

## Taxes, discounts, and fees

Use the **Checkout** tab to configure taxes, discounts, and fees for each item so customers see accurate pricing during checkout.
