# Scheduling price changes

Price changes are the heart of Launch Flow. You select the products or collections, set the new prices, and choose when they go live.

Unlike Shopify's built-in discount codes, Launch Flow changes the **actual listed price** of the product. That means the new price shows everywhere the product appears: collection pages, search, product pages without the customer needing to enter a code at checkout.

### How it works

* Launch Flow records the current price as a snapshot.
* At the start time, it writes the new price to each selected product.
* If you set an end time, it restores the snapshot price when the promotion ends.

{% hint style="warning" %}
**Avoid editing the same products elsewhere mid-launch.** If you manually change a price (or another app does) while a Launch Flow promotion is live, the snapshot may no longer reflect what you expect when it's time to roll back. Make price edits to those products through Launch Flow while a launch is active.

## 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://code-collective.gitbook.io/launch-flow/features/price-changes.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.
