Hi. My store sells wine and cider. For shipping reasons we need to sell wine in boxes of 6 or 12. We were using the minimum quantity at the cart level and a quantity step of 6 to achieve this.
However we recently started selling cans. I want to sell a box of 24 cans, and I want one box of cans to be enough to proceed to the checkout. We still want the other rules to apply to bottles of wine (6 or 12).
