How to price a mixed case without giving away your margin

To price a mixed case, pick a discount that your average margin can carry (often around 10% off any 12 bottles, sometimes a smaller tier at 6), decide which products qualify, exclude anything already discounted or allocated, check your state allows quantity discounts, and set the rule in your POS so the register applies it automatically. Below are the numbers to check before you put it on a sign.

Key takeaways

• Start from your blended margin on qualifying wines, not from a round number.
• Use tiers (6 and 12) to lift basket size without discounting every visit.
• Exclusions protect you: sale items, allocated bottles and loss leaders.
• Automate it, or it will be applied inconsistently.

Why mixed cases matter

The mixed case is one of the few promotions customers ask for by name. It does three things for a bottle shop:

1. Raises basket size. A customer who came for two bottles leaves with six or twelve.
2. Moves the middle of the shelf. Customers fill a case with bottles they would not buy alone.
3. Builds a habit. “I’ll do my case on Saturday” is a regular’s sentence.

The risk is the opposite: a discount that is too generous, applied to the wrong bottles, or applied by hand differently by every cashier.

Step 1: Work out what you can afford

Take the wines that will qualify and look at your blended gross margin on them. Suppose your qualifying wines average a 33% margin: a bottle you sell for 15.00 cost you about 10.00.

A 10% case discount takes 1.50 off that bottle. Your margin on the discounted bottle becomes 3.50 on 13.50, about 26%. That is the cost of the promotion on every bottle in the case.

Now the question is whether the case brings enough extra bottles. If customers who buy cases would otherwise have bought four bottles, a 12-bottle case adds eight sales at a 26% margin. That is a very good trade. If they would have bought ten anyway, it is a poor one.

Rule of thumb: the discount should be smaller than the share of the case that is extra business.

Step 2: Use tiers instead of one big discount

Two tiers work well for most shops:

Bottles in the basket	Discount	Purpose
6 to 11	small (for example 5%)	Rewards a half case, nudges toward 12
12 or more	larger (for example 10%)	The classic case price

Tiers stop you giving the full case discount to a six-bottle basket and give customers a reason to add the extra bottles. Only the highest tier that applies is used.

Step 3: Decide what qualifies

Write the rule in one sentence before you configure it:

“Any 12 bottles of still or sparkling wine, 750 ml, excluding items already on sale and allocated bottles.”

Typical choices:

• Include: a whole category (Wine) or sub-categories (Red, White, Sparkling).
• Exclude: items on markdown, allocated or limited bottles, and anything you already sell at a thin margin.
• Size: decide whether magnums count as one bottle or two, and say so on the sign.

Step 4: Check your state’s rules

Quantity discounts on alcohol are not allowed everywhere. Some states prohibit or limit volume discounts on certain products, some require posted prices, and control states may limit what you can sell in the first place. Before running a promotion:

1. Check your state alcohol beverage control agency’s guidance.
2. Check whether the rule differs for wine, beer and spirits.
3. If you run stores in two states, set the rule per store.

Our state alcohol rules page explains how the register’s switches map to common rule types.

Step 5: Automate it at the register

A mixed-case discount applied by hand will be applied wrong. One cashier forgets, another applies it to 11 bottles, a third adds it on top of a markdown.

In Bottle Shop POS, a mix-and-match rule holds the tiers, the qualifying categories, the exclusions, the stores and the dates. The register counts qualifying items as they are scanned and applies the right tier on its own. The receipt shows each bottle’s shelf price and the case discount as a separate line, and the discount report shows totals per rule, so you can judge whether the promotion paid.

Try it in the interactive case on the mix-and-match page, or follow the setup guide Set up a mix-and-match case discount.

Step 6: Measure after a month

Look at three numbers before and after:

• Average bottles per wine transaction. Did it go up?
• Gross margin on wine. How much did it go down?
• Discount total per rule. What did the promotion cost?

If baskets grew and margin dollars grew, keep it. If margin dollars fell, make the 12-bottle tier smaller, tighten exclusions or drop the 6-bottle tier.

Signage that avoids arguments

Put the rule on the shelf in plain words:

“Mix any 12 wines, take 10% off. Excludes sale and allocated items.”

Customers and cashiers then agree on what the register will do before the bottles reach the counter.

The short version

Price the case from your margin, use two tiers, exclude what hurts, check your state, and let the register do the counting. Then measure it, because a promotion you cannot measure is just a discount.
