# Find customers by purchase volume in a store

> Target customers by how many items they bought in one store, in a given period.

Volume-based targeting picks customers out by *how much* they bought rather than *what* they bought — for example everyone who bought between 100 and 200 items in one store during September.

## What you'll build

## Segment criteria

| Attribute     | What it does here                             |
| ------------- | --------------------------------------------- |
| Items bought  | Sets the volume range, for example 100 to 200 |
| Store         | Restricts the count to one store              |
| Purchase date | Sets the period, for example September        |

## Steps

    ### Start a new campaign

    ### Add a Channel block and connect it to the Member Segment block
  </Step>

  <Step>
    ### Run the campaign

    Wait for the execution to finish, then download the outcome and check the results.

## Variations

| Instead of       | Change                                                            |
| ---------------- | ----------------------------------------------------------------- |
| One store        | Drop the Store condition for a chain-wide or programme-wide count |
| A calendar month | Any Purchase date window                                          |
| A range          | A single lower bound, to catch every high-volume shopper          |
