I have three categories – wines, juices and teas. Wines and juices can be sold in a combination of 6 (those items/categories can be mixed). And teas are not allowed to enter this condition and can be sold in any quantities. Specifically, it is Ok 3 wines and 3 juices, it’s ok 6 wines, ok it’s 6 juices, but it’s not ok is 3 wines and 3 teas. Is this possible and how?
