The change
Variant swaps the bundle offer for a bundle builder
Simplified mockup drawn by LiftArchive from the shared screenshots.
Control
The original bundle setup. The post does not show what it looked like.
Variant
A bundle builder that lets shoppers put together their own bundle. The design and discount levels were not shared.
Why it likely won
Our reading of the result, not the practitioner's claim.
- a builder lets shoppers pick their own mix, which makes a bigger basket feel like their choice.
- lifting both conversion and order value suggests the builder helped undecided shoppers as well as raising basket size.
Caveats: Statistical significance was 85%, below the common 95% bar. Sample size, duration and the bundle offer itself were not shared.

How to run this test on your store
- Hypothesis
- If we replace our fixed bundle offer with a bundle builder, then revenue per visitor will rise because shoppers can build a larger order that suits them.
- Primary metric
- Revenue per visitor
- Guardrails
- Profit per visitor
- Average order value
- Refund rate
- Who should test it
- Stores with several products or flavours that are bought together or replenished. Stores with one hero product and nothing to combine probably won't benefit.
Questions
Do bundle builders increase average order value?
In this test, yes. Average order value rose 6.39% and revenue per visitor 14.11%.
Do bundle discounts hurt profit?
Not here. Profit per visitor rose 15.14%, slightly more than revenue per visitor.
Was the bundle builder result significant?
It reached 85% significance, which is below the usual 95%, so treat it as a strong signal rather than proof.
