Coupon Multiple Discount Eligibility Online Store Qualify
I have created a 20% off coupon with a customer usage limit of one (each customer can only use the coupon once). But when the customer tries to use it, the coupon only applies the 20% off to one item instead of the whole order. What am I doing wrong?
Edit the coupon and look for the Allow Multiple Discounts checkbox. This controls whether the Coupon Discount may apply multiple times in a single order, or just once. If this option is on, the Coupon Discount applies to all qualifying products. If this option is off, the Coupon Discount applies to only the most expensive qualifying product.
