If your store uses price groups to support multiple currencies, you can specify that a promotion applies only to items purchased in specific currencies. For example, you can create an order discount called “Spend 100 Euros, get 10 Euros off” that applies to the product prices in all price groups that contain the currency Euro.

When you create a promotion, you use the Price Groups field to specify the price groups for which the promotion is valid.

If you select one or more price groups, the promotion is valid only for those price groups. If you leave the Price Groups field blank, the promotion is valid for all price groups.

Note: Promotions you created in earlier releases are automatically valid for all price groups. If you create different price groups and want to make an existing promotion valid only for specific groups, you must edit the promotion and specify those price groups.
