we are using coupon codes to give discount for customers.
we created coupon code with 50 $ discount for orders with amount less than 500 $
but when one customer buy one product and when he applied that coupon code, he get "50 $" discount. that's fine
but when we buy 2 products , he will get less than "50 $" discount.
sometimes 26, 34, 48 $ ...etc.
any idea on what's wrong?
