I called and asked.
The MOPARTS15 code is still good.
It works online or over the phone, either one, anytime.
It stacks with the volume discounts.
5% for orders over $500
10% for orders over $1000.

This means that anytime you place an order for over $1000, you can use this code to get 25% off.


That's great for when there isn't a 30% code active.
