# The Straddle

Increase and decrease the price of every product by 10%. This is a great place to start as it will give you a look at elasticity across the board. If you don't want to start with your entire store, pick a few products or a collection to test first and iterate from there. Check out this [case study](https://blog.intelligems.io/intelli-blog/drive-conversions-revenue-through-price-decreases) on a brand who recently ran this type of test on their main collection and found that the lower price group generated nearly a 40% lift in conversion rate which yielded a 15% increase in revenue.

*What this test design might look like:*

|               | **Control Price** | **+10%** | **-10%** |
| ------------- | ----------------- | -------- | -------- |
| **Product A** | $10               | $11      | $9       |
| **Product B** | $20               | $22      | $18      |

{% hint style="info" %}
The Control Group should almost always be equal to what is currently live on the site - keeping one group consistent will keep your baseline consistent, giving you the most actionable results.
{% endhint %}

## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.

Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter:

```
GET https://docs.intelligems.io/getting-started/common-use-cases/price-test-common-use-cases/the-straddle.md?ask=<question>&goal=<endgoal>
```

`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal.

The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.

Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
