When you select this option the following member discount percent textbox and member role dropdown list will be displayed:
Member Discount Percentage – Member discounts are automatically applied to the order subtotal and do not require the customer to enter a coupon code based on the percentage entered in this box. Percentages should be entered as numbers without the percent sign. For example, a twenty percent discount should be entered as 20 and a ten percent discount should be entered as 10.
Member Discount Role – When you enter a value in the discount percentage field and choose a role from the dropdown box the cart will automatically apply a discount to the customer’s order during checkout.
