Terms and Conditions

Payment Terms

New Customers: New customers can pay with credit card (Master Card, Visa, American Express, or Discover), or prepay by check.

See our warranty page.


Rush Service

A minimum of $150 is added for Rush Service. For items over $600, Rush Service is 25% of the repair price.  Typical turnaround time for a Rush order is 3-5 business days from the time the quote is approved (dependent on  shop volume and parts availability). Your order is placed first in the repair queue, ahead of all non-rush orders, and will receive priority processing from our Purchasing department. 

Rush fees do not include expedited return  shipping or purchasing parts with next day or second day delivery.  Those delivery choices are an additional expense to the customer if desired; if a customer requires expedited return shipping, it must be noted at the time of approval and the cost is the responsibility of the customer. 


Shipping and Handling

Shipping charges will be added to the invoice at time of shipment.  Your preferred shipping account and method can be provided at time of approval; our default return shipping method is UPS Ground, unless otherwise stated.  A $5 handling charge will be applied to all shipments.
