# Showing % saved at each quantity price break: more add-to-carts

- Outcome: Won
- Page type: Product page (Ecommerce)
- Elements: Pricing, discounts & savings display, Bundles & quantity breaks
- Test run by: [REO](https://liftarchive.com/practitioners/reo/)

Showing the percentage saved at each higher quantity price break led to a noticeable rise in add-to-carts and conversions, but no figure was shared. REO ran this test for Accu, an online supplier of precision engineering components, and it was published as a VWO case study. The team had expected only a small gain.

## Result

**more add-to-carts**

- Add-to-carts: increased, but no percentage was shared.
- Overall conversions: increased, but no percentage was shared.
- The source describes the result as much stronger than expected. Without numbers, we can't say how big the lift was.

## Control

The product page listed quantity price breaks without pointing out how much buyers would save at each level.

## Variant

Simple visual cues showed the percentage saved as buyers moved up the price breaks, for example a five percent off message.

## Why it likely won (our reading)

- Buyers had to work out the savings themselves. A percentage makes the benefit clear at a glance.
- Engineering buyers often order in quantity, so a visible saving can tip them to a higher break.
- Percentages are easier to compare than unit prices across several tiers.

## Caveats

No figures, sample size, duration or significance level were shared. Accu sells mostly to engineers and businesses, so results may differ for consumer stores.

## How to run this test

- Hypothesis: If we show the percentage saved at each quantity price break, then more buyers will add to cart and order more because the value of buying in bulk is obvious.
- Primary metric: Add to Cart rate on product pages
- Guardrail: Conversion rate
- Guardrail: Average order quantity
- Guardrail: Average order value
- Who should test it: Stores with tiered quantity pricing, such as parts, supplies or consumables. Stores that sell mostly single items won't have price breaks to highlight.
