Test run byOliver KenyonConversionwise
Commentary byLiftArchiveOur analysis, not theirsAdding arrows to the cart upsell carousel and a one-line delivery window was reported at about $127,867 extra revenue a month. Oliver Kenyon ran this test in a cart drawer. The variant earned $8.56 revenue per session, but the control figure was not shared.
- Monthly revenue: about $127,867 extra, based on the team's forecast.
- Yearly revenue: about $1.53M, a forecast rather than banked revenue.
- Revenue per session: $8.56 for the variant. This is a level, not a lift, and the control figure was not given.
- Upsell take rate, conversion rate and average order value were not shared.
The change
The cart gains a delivery window line and arrows to browse upsells.
Simplified mockup drawn by LiftArchive from the shared screenshots.
Control
The cart drawer without arrows on the upsell section and without a line saying when the order would ship. Only the variant was shown in the post.
Variant
Left and right arrows were added under the "You may also like" upsell so shoppers could browse more add-ons. A line under the cart item read "In stock, Ships within 1-3 business days".
Why it likely won
Our reading of the result, not the practitioner's claim.
- arrows signal there are more add-ons to see, so shoppers browse past the first one.
- a delivery window answers a key question right before checkout and may cut abandonment.
- "In stock" adds quiet reassurance without pushing urgency.
Caveats: Two changes shipped together, and no before image was shared. Sample size, test length and the control's revenue per session were not shared, so the size of the lift can't be checked.

How to run this test on your store
- Hypothesis
- If we add browse arrows to cart upsells and show a delivery window under each item, then revenue per session will rise because shoppers explore more add-ons and feel sure about when the order will arrive.
- Primary metric
- Revenue per session
- Guardrails
- Average order value
- Checkout start rate
- Late delivery complaints
- Who should test it
- Stores with a cart drawer upsell carousel and reliable shipping times. If you can't commit to a delivery window, the extra line could create complaints.
Questions
Should you show delivery times in the cart?
In this test, a line saying the item was in stock and shipped within 1-3 business days was one of two changes in a winning cart test.
How do you get more clicks on cart upsells?
Kenyon's team added small arrows so shoppers could scroll through more add-ons. The separate effect of the arrows was not reported.
What is a good revenue per session for a cart test?
This variant reported $8.56 per session, but without the control figure it can't be read as a lift. Always compare against your own baseline.
