Price groups enable you to offer special pricing to select customers. You might want to give your especially good customers an extra 5% off the price of some products.
To run a special sale for only certain customers, create a price group, assign those customers to it, specify the discount, and select the products where the discount will apply. When the sale ends, delete the price group. The customers and products will not be deleted from your store — only the assignment to the group will be cleared.
Click Add Group to create a new price group. You can create as many groups as you want or need.
Before you can add someone to a group they must be in your Customers list.
