# Cart groups

Cart groups allow you to create a group based on conditions that you can set up through our easy-to-use rule builder interface.

For each group that you create, the following computed variables are available to you in the rule builder interface under the Rules section.

1. Total cart amount → Cart amount for the group, inclusive of discounts
2. Subtotal cart amount → Cart amount for the group, exclusive of discounts
3. Line count → Count of line items 
4. Quantity sum → Total sum of quantity of items matching cart group rules.
5. Unique product count → Unique products in the user's cart matching the group rules. 
6. Unique variant count → Unique variants in the user's cart matching the group rules.

{% hint style="info" %}
Currently we do not support nesting conditions as this is still in early Beta. The AND / OR logic is set on the entire sub level and not on a per condition basis.&#x20;
