'Du sparst' euro savings line under bundle price: +1.8% RPU
Test run byDRIP AgencyCRO agency
Commentary byLiftArchiveOur analysis, not theirsAdding an explicit euro savings line below the bundle price on BLACKROLL product pages lifted revenue per user by 1.8%.
DRIP Agency ran this test for BLACKROLL and published it in its own case study.
Before the change, the bundle saving was only implied by the price.
- Revenue per user: +1.8%.
- Extra revenue during the test: about EUR 27.9K. That is revenue during the runtime, not annualised.
- Significance, sample size and test length were not shared.
The change
A euro savings line appears directly under the bundle price.
Simplified mockup drawn by LiftArchive from the shared screenshots.
Control
The product page showed the bundle price. Any saving was built into the number, so shoppers had to work it out themselves.
Variant
A line directly below the price stated the saving as a euro amount, starting with "Du sparst" ("You save").
Why it likely won
Our reading of the result, not the practitioner's claim.
- Shoppers no longer had to do mental math to see the bundle's value.
- DRIP notes these products cost under EUR 100. At that price, a euro amount can feel more concrete than a percentage.
- Value for money came up as a common concern in DRIP's customer research.
Caveats: Vendor-reported result. Revenue is for the test runtime only, and significance, sample size and duration were not stated.

How to run this test on your store
- Hypothesis
- If we state the bundle saving as a currency amount under the price, then revenue per user will rise because shoppers see the value without calculating it.
- Primary metric
- Revenue per user
- Guardrails
- Bundle take rate
- Average order value
- Conversion rate
- Who should test it
- Stores that sell bundles or multi-packs at a discount but don't spell the saving out. Test percent versus amount: for high-priced items a percentage may read bigger.
Questions
Should I show savings as a percent or an amount?
A common rule of thumb is amounts for cheaper items and percentages for pricier ones, whichever number looks bigger.
BLACKROLL's products here were under EUR 100 and the euro amount won.
Where should a savings message go?
Right next to the price, where shoppers are already judging value.
In this test it sat directly below the price.
