## Enable Promotion Support

Make sure to enable promotion support for large carts. Otherwise, promotions aren’t evaluated for carts with a total quantity of more than 10,000. To request promotion support for large carts, contact your Salesforce Administrator.

## Understand Changes to Promotion Functionality

After you enable promotion support for large carts, promotions ignore quantity limits on discounts, which can impact certain promotion scenarios. Here are some examples.

- Total Fixed Price discounts–When you create a Total Fixed Price discount, you set a quantity limit to offer a select number of items for a specific reduced rate. For example, you offer three shirts for $50. Because the promotion evaluator ignores quantity limits for large carts, Total Fixed Price promotions sometimes result in either no discount or a larger discount than expected. If you enable promotion support for large carts, we recommend not using Total Fixed Price discounts.
- Percent Off, Fixed Amount Off Unit, and Fixed Price discounts–Quantity limits are ignored, so discounts apply to all items that meet the conditions. For example, you offer a 10% discount on an item priced at $10, but limit the quantity to one. If a customer adds a quantity of 10 for this item, the result is a $10 discount.
- Buy 1, Get 1–Because quantity is ignored on a line item, a line item counts as only one qualifying item. Therefore, two items with the same SKU don’t qualify for a “Buy 1, Get 1” promotion. Instead, consider creating promotions for “Buy X, Get Y.”
