Notice for local customers: As long as required, we are closed to local pick-ups. We are able to make arrangements to get your parts to you by shipping or other methods. Please contact us for options.
Due to the present COVID-19 (coronavirus) pandemic, our first priority is to keep our employees and customers safe. At this point, the majority of our staff are working at home - with minimal staff at our facilities.
We are still shipping orders of in-stock items. However, there may be delays in deliveries that are beyond our control. No refunds for delayed shipments. Also, if you are a business that is closed due to government mandate, the shipping companies will likely not deliver and if your shipment is returned to us because it cannot deliver, you will be responsible to pay all related shipping/handling charges... If your order needs to be drop-shipped, we will try to advise you of any delays that may be encountered. If anything changes, we will post updates as soon as possible.
Our thoughts and prayers go out to those who are being affected by the virus.
