Adding 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.

## Result

**+1.8% RPU**

- 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.

## 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)

- 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

- 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
- Guardrail: Bundle take rate
- Guardrail: Average order value
- Guardrail: 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.
