Commentary byLiftArchiveOur analysis, not theirsRedesigning the slide cart, removing a $25 pre-checkout upsell pop-up and adding trust signals raised revenue per session by $1.10. Oliver Kenyon ran this test on a store with a $300 average order value. It was forecast at about $31,000 a month.
- Revenue per session rose by $1.10.
- Forecast revenue: about +$31,000 a month, or +$372,000 a year. These are projections.
- Several changes were bundled, so the effect of removing the upsell alone is unknown.
The change
The upsell pop-up is gone and the cart gains milestones, trust lines and payment icons.
Simplified mockup drawn by LiftArchive from the shared screenshots.
Control
The slide cart had a plain progress bar, a cross-sell row, the subtotal and checkout button, and an Afterpay note. A $25 upsell pop-up appeared before checkout.
Variant
The upsell pop-up was removed. The cart gained a tiered progress bar with $150 and $200 milestones, a cross-sell carousel with prices, a returns and shipping line, and payment icons under the checkout button.
Why it likely won
Our reading of the result, not the practitioner's claim.
- a $25 add-on pop-up was small next to a $300 order, so it interrupted buyers without adding much value.
- returns, shipping and payment icons near the checkout button eased last-minute doubts.
- a cleaner cart made the step from cart to checkout feel smoother, where the team had seen drop-off.
Caveats: Sample size, test length and significance were not shared, and the dollar figures are forecasts. Many changes were tested at once.

How to run this test on your store
- Hypothesis
- If we remove the pre-checkout upsell pop-up and add trust signals to the slide cart, then revenue per session will rise because fewer shoppers drop off between cart and checkout.
- Primary metric
- Revenue per session
- Guardrails
- Average order value
- Upsell attach rate
- Cart-to-checkout rate
- Who should test it
- Stores that see drop-off between cart and checkout, especially if a pop-up upsell is cheap relative to their order value. If your upsell is well matched and drives real AOV, test it on its own before removing it.
Questions
Should I remove a pre-checkout upsell pop-up?
Here removing a $25 upsell on a $300 AOV store was part of a change that lifted revenue per session by $1.10. If the upsell is small relative to the order, it may cost more in friction than it adds.
What trust signals belong in a slide cart?
This variant added a returns and shipping line under the subtotal and payment icons under the checkout button.
Can I tell which cart change worked?
No. The redesign, the upsell removal and the trust elements were tested together.
