Spend-to-unlock discount banner in basket: +7% revenue
Commentary byLiftArchiveOur analysis, not theirsA green banner on the basket page, telling shoppers how much more they needed to spend to unlock a discount, lifted average basket value by 8% and revenue by 7%.
Urban Decay's digital team ran this A/B test during a sale, with support from the testing vendor's customer success team.
It was published as a VWO case study.
- Average basket value: +8%. Shoppers added more to reach the threshold.
- Items per basket: +7%. The extra value came from more products, not just pricier ones.
- Revenue: +7%. The vendor estimated the change would be worth about 190,000 euros over a year; that is a projection, not a measured result.
The change
Variant adds a spend-to-unlock discount banner above the basket items.
Simplified mockup drawn by LiftArchive from the shared screenshots.
Control
During a sale, the basket page showed the usual cart contents with no message about a spend threshold.
Variant
Shoppers with less than 85 euros in their basket saw a green banner at the top of the basket page. It read "Only X more euros until you can benefit from a discount on your purchase!" with the gap filled in.
Why it likely won
Our reading of the result, not the practitioner's claim.
- Showing the exact gap turns a vague offer into a small, concrete goal.
- Shoppers in a sale are already in a buying mood, so a nudge to add one more item lands well.
- The banner sat where shoppers review their order, the moment they decide whether to add more.
Caveats: The test ran during a sale, so the effect may be smaller at full price. No sample size, duration or confidence level was shared, and the yearly revenue figure is a vendor projection.

How to run this test on your store
- Hypothesis
- If we show shoppers below a spend threshold how much more they need to add to unlock a discount, then average order value will rise because the gap becomes a clear, reachable goal.
- Primary metric
- Revenue per visitor
- Guardrails
- Checkout conversion rate
- Discount cost as a share of revenue
- Return rate
- Who should test it
- Stores with a typical basket somewhat below a sensible threshold, especially during sales. It probably won't help if most orders are single items far below the threshold, or if margins can't absorb the discount.
Questions
Where should a spend threshold be set?
A common starting point is a little above your current average order value.
Too high and shoppers ignore it; too low and you give away margin on orders that would have happened anyway.
Does a threshold banner work outside of sales?
This test only ran during a sale, so it doesn't answer that.
Test it separately at full price before assuming the same lift.
Should the banner show the exact amount left?
Showing the exact gap, as Urban Decay did, makes the goal concrete.
Update it as items are added so it stays accurate.
