# Overview

When you setup your product options and use the **Adjust price** selection, you can choose one of 5 ways to handle the quantities.

Select **Show Advanced Settings **from within the app admin while you are creating or editing an option to view these options.

Select an option below to view more information about each.

## Option quantity matches product quantity

When using this selection, the number of products the customer has chosen will determine the number of options that are added (**IE.** 1 product = 1 option).

The **quantity and price** will display in the checkout as a total for the product combined with its option, and the **subtotal** will show the total of all products and options combined as one amount.

**Example - Product Page**

The **Total Extras** will display 1x the option price even if the quantity selector is 1 or more.

**Example - Cart Page**

Each row of the cart will display one product, its quantity, and the cost of your options.

The cart will display the **subtotal** as the entire cart's total.

The **quantity and price** will display in the checkout as a total for the product combined with its options, and the **subtotal** will show the product totals and the options totals as two separate amounts.

The quantity entered will be multiplied based on the quantity of base product chosen.
