Hello, i have a question. i configured a rule on my woocomerce->coupon (for example apply a coupon discount when min spend is 27$). Now when I want to pay the bill, always appear: do you have any coupon? please enter the code....... Then i only want that this message appear only when the bill is >27$.
Thanks
