This Campaign is going to be used strictly for reporting purposes, and will be incorporating the use of Performance Mode in order to give you the average time between a contact's initial opt in and their initial purchase.
Note: Due to the nature of the Trigger you'll be using, this Campaign will only apply to Contacts that are added to your database going forward, so make sure to add an "End" Element after the "Added to Campaign" Trigger!

3. Once the Goal element has been added, choose the "A field is updated" selection:
4. Select the "Spent" field from the Field dropdown menu:

Select "Field is this value", and choose the following options:
6. Lastly, place an "End" Element after the Goal:

After the Campaign has been running for a little while, choose the "Goal Conversion Time" Report to see the average time between opt in and initial purchase:
