Confetti on the biggest bundle: +6.32% revenue per visitor
Test run byDave DiederenSyntra Labs
Commentary byLiftArchiveOur analysis, not theirsShowing a quick confetti effect and a 'biggest savings unlocked' message when shoppers picked the largest bundle lifted revenue per visitor by 6.32% and conversion rate by 5.47%. Dave Diederen ran this test on a product page bundle selector. The offer itself did not change, only the feedback after choosing it.
- Revenue per visitor: +6.32% ($2.59 to $2.76), with a range of +2% to +29%. The whole range is positive, a fairly firm win.
- Conversion rate: +5.47% (2.37% to 2.50%), range +1% to +21%. More visitors went on to buy.
- Average order value and the share of shoppers picking the largest bundle were not shared, so we can't tell whether the gain came from bigger bundles or more orders.
The change
The variant fires confetti and a savings message when the largest bundle is picked.
Simplified mockup drawn by LiftArchive from the shared screenshots.
Control
A standard bundle selector: picking an option simply updated the price, with no extra feedback.
Variant
Choosing the largest bundle triggered a short confetti animation and a message saying the shopper had unlocked the biggest savings. Other options behaved as before.
Why it likely won
Our reading of the result, not the practitioner's claim.
- picking the biggest bundle means spending more, and instant positive feedback reassures shoppers they made a smart call.
- the message turns a price change into a clear win by naming the saving, which can ease second thoughts before checkout.
- the timing matters. The reward lands at the exact moment of commitment, not later in the cart.
Caveats: Sample size, test length and the bundle prices were not shared, and the design of the effect was not shown. The result comes from a single test.

How to run this test on your store
- Hypothesis
- If we show a celebration effect and a savings message when shoppers pick the largest bundle, then more will buy because the bigger commitment feels rewarded instead of risky.
- Primary metric
- Revenue per visitor
- Guardrails
- Average order value
- Share of orders on the largest bundle
- Page speed on mobile
- Who should test it
- Stores with a quantity or bundle selector where the largest option gives a real saving, such as supplements, beauty or consumables. It may feel out of place for luxury brands, and it won't apply without a tiered offer.
Questions
Do animations like confetti increase conversions?
In this test, confetti tied to picking the largest bundle lifted conversion 5.47% and revenue per visitor 6.32%. It worked as feedback at a key decision, not as decoration.
How do you get more shoppers to choose a bigger bundle?
One approach is to reward the choice when it happens. Here a short celebration and a 'biggest savings' message made the larger option feel like the smart pick.
Does a bundle celebration effect hurt page speed?
The post doesn't say. Keep the animation light and track mobile load time as a guardrail.
