- Primarily sells single items and struggles to make a profit on the first order
- Considering a volume discount or bundles, but unsure how to structure the tiers
- Wants to understand the difference between volume discounts, bundles, mix and match, and gift with purchase
- Wants to know how to calculate an offer before it goes live
The four are used interchangeably, but they solve different problems:
- Volume discount (tiered pricing): The more of the same item, the lower the price per unit. For example, "buy 2, save 10%" and "buy 3, save 15%".
- Bundle (package deal): Fixed products sold together for a single price.
- Mix and match: The customer chooses items from a group for a combined price.
- Gift with purchase ("buy 2, get 1 free"): An item is given for free when the cart reaches a certain quantity or amount.
What they all have in common is that they increase the cart size instead of simply lowering the price.
A single item often carries the entire shipping cost and the full acquisition cost on its own. This can make a first order a loss, even when the item has a decent margin.
A hypothetical example. An item costs 120 DKK excl. VAT. The cost of goods is 40 DKK, shipping is 35 DKK per package, the payment fee is approximately 2.5%, and a new customer costs 80 DKK to acquire.
1 item for 120 DKK
- Revenue 120 DKK, cost of goods 40 DKK, shipping 35 DKK, fee 3 DKK.
- Contribution margin: 42 DKK.
- After the acquisition cost of 80 DKK: minus 38 DKK.
2 items with 10% discount
- Revenue 216 DKK, cost of goods 80 DKK, shipping 35 DKK, fee 5 DKK.
- Contribution margin: 96 DKK.
- After the acquisition cost: plus 16 DKK.
3 items with 15% discount
- Revenue 306 DKK, cost of goods 120 DKK, shipping 35 DKK, fee 8 DKK.
- Contribution margin: 143 DKK.
- After the acquisition cost: plus 63 DKK.
The price per item fell, but the order became more profitable because the shipping and acquisition costs are the same, regardless of whether the cart contains one, two, or three items. It is the cart size that determines the profit, not the price. Always calculate based on your own figures.
- See your basket sizes today. How many customers buy 1, 2, and 3 or more items?
- Calculate the contribution margin per basket size after product costs, shipping, and payment fees.
- Subtract the acquisition cost, and find the basket value where the order becomes profitable. This is your break-even basket value.
- Set the tiers, so the basket size you want more people to reach is above break-even. Check each tier with the formula in Discount and Contribution Margin.
- Calculate what a free item actually costs. It is the purchase price plus any personalization, not a percentage of the retail price.
- Check what proportion of baskets needs to be increased, before the offer pays off. Customers who would have bought more anyway do not count as an uplift.
Finally, measure what the first order leaves behind in relation to what a new customer costs, before and after the offer.
- Display all products in a bundle clearly. A small collage image is not enough. Give each bundle its own visual identity.
- Create a small starter pack. A curated sample pack can lower the barrier for a cold lead.
An offer no one can see won't work. Display it where your traffic lands:
- Product page: The offer should be visible before the customer adds the item to their cart.
- Collection page: So the offer meets those who are browsing.
- Cart: Add a "X amount to free shipping" indicator so the customer can see how close they are to the next step.
- Ads: Communicate the offer in your ads. It gives the buyer an extra reason to purchase.
When order value increases, your ads have more room to breathe. This allows us to test more angles, hooks, and concepts without squeezing unit economics, and we can justify a slightly higher acquisition cost because the order value supports it.

DVISIONMEDIA's approach
We build offers based on the math, not a gut feeling. We start with cart sizes, calculate the contribution margin per cart, find the break-even cart value, and check what a free item actually costs before the offer goes live. The goal is an offer that is profitable on the first order, so the order value covers the acquisition cost. This is part of the approach we build into our strategy work through E-COM OS.
1. What is a volume discount?
A volume discount lowers the price per unit the more of the same item a customer buys, for example, "buy 2, save 10%" and "buy 3, save 15%".
2. What is the difference between a volume discount and a bundle?
A volume discount applies to multiple units of the same item. A bundle consists of fixed products sold together for a single price. Both increase cart size.
3. How do I know if a discount tier is profitable?
Calculate the contribution margin for the entire cart after cost of goods, shipping, and fees, subtract the acquisition cost, and see if the order is profitable. Check the step using the break-even formula.
4. What does a free item cost in a "buy 2, get 1 free" offer?
It costs what you paid to purchase it, plus any personalization. It is not a percentage of the retail price.
5. Where should the offer be displayed?
Where the traffic lands: on the product page, in the collection, and in the cart.
