15% off three flagship pillows: +42.5% conversion rate
Test run byClean CommitCRO agency
Commentary byLiftArchiveOur analysis, not theirsA 15% discount on three flagship pillows lifted conversion rate by 42.5% and revenue per visitor by 33.4% against full price.
Clean Commit ran this price test for the bedding brand Quiet Mind, and it was published as a Shoplift case study.
Over 20 days and 13,843 visitors, the result reached statistical significance.
- Conversion rate: +42.5%, with 228 purchases in the discount group against 159 at full price.
- Revenue per visitor: +33.4% overall. Returning customers showed a bigger lift of +62.4%.
- Add-to-cart rate: +17.9%.
- The source extrapolates this to $151,840 a year in extra revenue. Clean Commit's own margin analysis put the profit gain at about $53,000 a year. Both are projections, not measured results.
The change
Same page; only the price is 15% lower, carried through cart and checkout.
Simplified mockup drawn by LiftArchive from the shared screenshots.
Control
The three flagship products showed their normal full price on the product page, cart and checkout.
Variant
The same three products showed a price 15% lower, applied consistently through product page, cart and checkout.
Why it likely won
Our reading of the result, not the practitioner's claim.
- Reviews already flagged price as one of the three most common complaints, so price was a real barrier for many shoppers.
- The brand had seen 25% discounts work before, which suggests the full price sat above what many shoppers were willing to pay.
- Returning visitors may have been waiting for a better price, so a lower one tipped them over.
- The conversion gain was big enough to outrun the lower price per order, which is why revenue per visitor still rose.
Caveats: This is a small store: the result rests on 387 purchases across both groups over 20 days. The annual revenue and profit figures are projections from the source, and a lower price cuts margin, so revenue per visitor alone does not prove the change is profitable.

How to run this test on your store
- Hypothesis
- If we lower the price of our flagship products by 15%, then revenue per visitor will rise because price is a common objection and the extra buyers outweigh the smaller margin per order.
- Primary metric
- Profit per visitor (revenue per visitor minus cost of goods)
- Guardrails
- Revenue per visitor
- Average order value
- Refund rate
- Who should test it
- Brands whose reviews or support tickets mention price often, or who have seen sales lift during discounts. It is a poor fit if your margins are thin or a lower price would clash with a premium position or reseller agreements.
Questions
Can lowering prices increase revenue?
Yes, if enough extra people buy to cover the smaller price per order.
In this test revenue per visitor rose 33.4% after a 15% cut.
How do you A/B test prices on Shopify?
You need a tool that shows each visitor one price everywhere: product page, cart and checkout.
Quiet Mind used Shoplift's price testing feature for this.
Should I judge a price test on revenue or profit?
Profit. A discount can raise revenue while shrinking margin, so check the gain against your cost of goods before rolling it out.
