A 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.

## Result

**+42.5% conversion rate**

- 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.

## 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)

- 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

- 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)
- Guardrail: Revenue per visitor
- Guardrail: Average order value
- Guardrail: 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.
