We'd like an upsell that nudges shoppers to fill a full case of wine. When someone has part of a case in their cart, they'd see a message like "Add 6 more bottles to your order at no extra freight cost!" To do this, the upsell criteria builder would need: Quantity in cart as a criteria option, with more than / less than rules (e.g. more than 6 and less than 12) Case price is set as a criteria option, so only items sold by the case are counted A dynamic bottle count in the message that works out how many more bottles are needed for the next case Support for multiple cases, not just the first (e.g. 18 to 23 bottles prompts a top-up to 24) Editable message wording This would help lift order value and make the most of freight costs on every order.
