Trust stats and clear savings in cart drawer: +$32,605/month
Test run byConvertiblesCRO agency
Commentary byLiftArchiveOur analysis, not theirsA cart drawer with clear applied-discount savings, a two-product upsell and a three-stat trust line above checkout added a reported $32,605 a month.
Convertibles ran this test for an 8-figure wellness and recovery brand.
The winner stacked several changes, and versions with only some of them did not clear control.
- Revenue: +$32,605 a month for the full stack, as reported by the agency.
- A version with only a cleaner layout and a bigger upsell did not clear control.
- Adding applied-discount savings on top of that did not clear control either.
- Adding a single review-score badge was still not enough. Only the three-stat trust line pushed it over.
The change
Applied savings, a two-product upsell and a three-stat trust line above checkout.
Simplified mockup drawn by LiftArchive from the shared screenshots.
Control
A bare drawer: free shipping progress bar, 'Buy 2 & save 15%' as a plain text link, a single-product upsell, and no trust signals.
Variant
A 'SAVE15% applied' badge on the product with the new price and a tooltip showing dollar savings, two upsells with struck-through prices, and a trust line above checkout: 15K+ reviews, 566K+ customers, 30-day returns.
Why it likely won
Our reading of the result, not the practitioner's claim.
- New buyers may not know the brand, so customer count, review count and a return window answer trust doubts at checkout.
- Showing the discount in dollars and the lower price makes the multi-buy offer feel real.
- Two upsells with struck prices made adding an item easier than a one-at-a-time carousel.
- Each layer alone was not enough; the combination may be what tipped shoppers.
Caveats: The winner stacks several changes, so the lift can't be credited to the trust line alone. No sample size, duration or confidence level was published.

How to run this test on your store
- Hypothesis
- If we add a compact trust line and show discount savings in dollars in the cart drawer, then revenue per visitor will rise because shoppers get answers to 'can I trust this brand' and 'should I add more' at the point of purchase.
- Primary metric
- Revenue per visitor among shoppers who open the cart
- Guardrails
- Conversion rate
- Average order value
- Discount usage rate
- Who should test it
- Brands with many first-time buyers and a bare cart drawer. If most buyers are repeat customers who already trust you, trust stats may add little.
Questions
Do trust signals clutter the cart drawer?
Not if they are short. The winner used three brief stats on one line above the checkout button.
What if we don't have big review or customer numbers?
Use your strongest credibility point, such as a guarantee or free returns, until the numbers grow.
Should the return policy appear in the cart?
Here, a 30-day returns note was part of the winning trust line.
Repeating it near checkout can ease last-step doubt.
