# Find customers by spend in a chain

> Target customers who spent over a threshold in one chain, in a recent window.

For a multi-chain programme, the usual question is "who has been spending in *this* chain lately". The chain is a parameter of the segment, not a different procedure.

## What you'll build

## Segment criteria

| Attribute     | What it does here                                             |
| ------------- | ------------------------------------------------------------- |
| Chain         | Restricts the segment to purchases made in the chain you pick |
| Amount spent  | Sets the spend threshold, for example 500 and above           |
| Purchase date | Sets the look-back window, for example the last 7 days        |

## Steps

<Steps>
  <Step>
    ### Start a new campaign

    Open the **Campaigns** tab and select **Add new campaign**.
  </Step>

  <Step>
    ### Add a Member Segment block and set Chain, Amount spent and Purchase date

    See [Audiences & Data](/business-documentation/audiences-and-data) for the segment builder.
  </Step>

  <Step>
    ### 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.
  </Step>
</Steps>

## Variations

The only thing that changes between chains is the value of the Chain attribute.

| Chain          | Threshold | Window      |
| -------------- | --------- | ----------- |
| Central Co-op  | 500+      | Last 7 days |
| Profi          | 500+      | Last 7 days |
| Southern Co-op | 500+      | Last 7 days |

<Info>
  **Migration note.** This page replaces **three** near-identical pages in the current wiki — one each for Central Co-op, Profi and Southern Co-op. They differed only in the chain name, and the Southern Co-op page in fact embedded the Profi page's screenshot, so the fork was already unmaintained.
