Thanks, Terran!

That seems to do the trick.

If anyone is curious about how I added this to the checkout receipt:

...
<div ng-init="transactions.subtotal=0">
  <ol>
    <li ng-repeat="checkout in circulations" |
ng-init="transactions.subtotal=transactions.subtotal --
checkout.copy.price" >
    ....
    </li>
  </ol>
    ....
<div>You Saved<br/>{{transactions.subtotal | currency}}</span><br/> by
borrowing from <br/> {{current_location.name}}!</div>
...
