Bundle Pricing Strategy: How to Increase Profit by Selling Sets
Acquiring a customer is expensive. In 2025, with rising ad costs (CPM), the only way to survive is to make every customer spend more.
Selling one item is good. Selling three at once is better. Bundle Pricing (often called "Kitting") is the most effective lever you have to increase Average Order Value (AOV) and lower your shipping costs relative to profit.
In this guide, we will move beyond the basic "Buy 2 Get 1 Free" and explore the psychology of value perception, the "Logistic Math" that makes bundles profitable, and how to execute this on Amazon vs. Shopify.
The Psychology: Reducing the "Pain of Paying"
Every time a customer decides to buy something, they experience a micro-moment of friction psychologists call the "Pain of Paying."
If you try to sell a Camera Body ($500), then a Lens ($300), then a Bag ($50), and then an SD Card ($20), you are forcing the customer to make four separate decisions. That is four chances for them to say "No" or "Maybe later."
The Bundle Solution: Offer a "Photographer Starter Kit" for $850.
The customer now makes one decision. They perceive the bundle as a single item—a "solution" to their problem—rather than a collection of costs.
The Math: Why 1+1=3 for Profit
New sellers think bundling is just about marketing. Experienced sellers know it's about Logistics.
Let's say you sell Shampoo bottles.
| Cost Item | Selling 1 Unit | Selling 3-Pack |
|---|---|---|
| Revenue | $20.00 | $54.00 (10% Off) |
| COGS | -$5.00 | -$15.00 |
| Shipping (The Key!) | -$8.00 | -$10.00 |
| Pick & Pack Labor | -$2.00 | -$2.50 |
| Net Profit | $5.00 | $26.50 |
By bundling, your profit didn't just triple ($15); it quintupled ($26.50) because you saved massively on shipping and labor. Shipping three bottles in one box is only slightly more expensive than shipping one.

Strategy 1: The "Mixed Bundle" (Nintendo Strategy)
Nintendo rarely discounts the Switch console. Instead, they sell a "Mario Kart Bundle."
They include the console (High Value) + a Game (High Perceived Value, Low Digital Cost) + a Case (Low Cost).
Action Step: Take your best-selling "Hero Product" and bundle it with a high-margin accessory that usually has a low conversion rate. The Hero Product drives the click; the accessory drives the profit.
Strategy 2: The "Dead Stock" Bundle
Do you have inventory that isn't moving? Don't just clearance it out. That hurts your brand image.
Instead, create a "Mystery Box" or a "Gift Set."
- Scenario: You sell socks. The red socks aren't selling.
- Tactic: Create a "Holiday 3-Pack" containing Black, Grey, and Red.
Customers who wouldn't buy the red socks individually will happily accept them as part of a value pack. You clear inventory without officially lowering the price of the red socks.
Strategy 3: The "Buy More, Save More" (Volume Tier)
This is standard for consumables (supplements, skincare, pet food).
- 1 Bottle: $30
- 3 Bottles: $80 (Save $10)
- 6 Bottles: $150 (Save $30)
The goal here is Customer Lifetime Value (LTV) acceleration. You are getting the customer to commit to 6 months of usage today. This takes them out of the market (they won't buy from competitors) and gives you cash flow immediately.
How to Implement by Platform
Amazon FBA
Amazon allows "Virtual Bundles" for Brand Registered sellers. This lets you combine two existing FBA ASINs into a new listing without physically repacking them.
Pros: No new inventory needed.
Cons: Amazon charges fulfillment fees on both items individually.
Shopify
Use apps like "Bundles.app" or "Rebuy." You can create a distinct SKU for the bundle.
Pro Tip: Physically pre-pack bundles in your warehouse to save on pick/pack fees.
Common Mistakes to Avoid
- The "Negative Math" Bundle: Don't bundle heavy items with low-margin items. If you bundle a 10lb dumbbell with a $5 water bottle, the extra shipping weight might eat the entire profit of the bottle.
- Over-Complicating: Don't let customers "Build Their Own Bundle" with too many choices. Paradox of choice kills conversion. Give them 3 curated options.
- Hiding the Savings: Don't just show the price. Explicitly say "Value: $100 | Your Price: $70." Use Anchor Pricing to highlight the deal.
FAQ
Should I stop selling the individual items?
Usually, no. You want to keep the individual items available at a high price. This serves as the "Anchor." If the individual item isn't available, the customer has no reference point to know the bundle is a good deal.
Does bundling work for high-ticket items?
Yes, but the discount percentage should be lower. On a $2,000 laptop, a "Free Mouse" (value $20) is often enough to tip the scale. You don't need to give 20% off.
How do I handle returns on bundles?
Your policy should state: "Bundles must be returned in full." Do not allow customers to keep the discounted camera and return the lens for full refund value. This is a common scam.
Conclusion
Bundling is the ultimate win-win.
For the customer, it simplifies the decision and offers value. For you, it creates a "moat" around your profitability. When competitors are fighting a price war on single units, you are selling profitable systems.
