I'm trying to set up a coupon on my site so that a total price of cart will be 79$ no matter whats in cart.
It should work only for current customers.
In my cart is: 1x product X, 2x product Y, total 200$ but coupon should change it to 79$
10 product X, total 1000$ but coupon should change it to 79$
Total price should be always 79$
