Test run byDave DiederenSyntra Labs
Commentary byLiftArchiveOur analysis, not theirsAdding a "You're saving $X on this order" line to a bundle selector lifted conversion rate by 11.26% in Dave Diederen's test. Revenue per visitor rose 12.53% and profit per visitor rose 10.55%. The line simply showed shoppers a saving they would otherwise have had to work out.
- Conversion rate: +11.26% (3.10% to 3.45%). More visitors bought.
- Revenue per visitor: +12.53% ($3.20 to $3.60). The tool estimated about $107,626 more revenue per month.
- Profit per visitor: +10.55% ($2.61 to $2.88).
- Average order value: +1.14% ($103.08 to $104.25). Roughly flat.
- A third arm, labelled "With Savings Badge & 4..." (cut off), reached 3.48% conversion but a lower $3.44 revenue per visitor and $98.63 order value. What it added isn't shared.
The change
The variant adds a savings line between the bundle options and the add-to-cart button.

Control
A bundle selector with pack options and prices, but no total saving shown for the order.
Variant
The same selector with a highlighted line under the options stating how much the shopper saves on the order.
Why it likely won
Our reading of the result, not the practitioner's claim.
- shoppers rarely do the maths on bundle deals. Stating the saving removes that work.
- an unanswered question like "how much am I saving?" is friction, even if nothing on the page is broken.
- a dollar figure for the whole order shows the full value of the deal, not just a per-unit discount.
Caveats: Sample size and test length were not shared. The ranges cross zero (-5% to +31% on conversion), and the store was not named.

How to run this test on your store
- Hypothesis
- If we show 'You're saving $X on this order' under the bundle selector, then more visitors will buy because the deal's value is clear without doing maths.
- Primary metric
- Revenue per visitor
- Guardrails
- Average order value
- Bundle take rate
- Profit per visitor
- Who should test it
- Stores with multi-pack or bundle pricing on the product page. It won't help much if your bundles offer only a tiny saving.
Questions
Should I show the total savings on a bundle?
In this test, stating the order saving raised conversion rate by 11.26% and revenue per visitor by 12.53%.
Where should the savings message go?
Dave Diederen's example puts it right under the bundle options, just above the add-to-cart button. That's where shoppers make their pick.
Is a strikethrough price enough to show the deal?
Diederen argues it often isn't, because shoppers still have to work out the saving. This test found that spelling it out helped.
