As of 2015, to order parts from the NAPA Auto Parts warehouse, visit the company's website, NAPAOnline.com. On the main page, enter a keyword, phrase or part number, or select the make of vehicle, and click on Search to find the needed part.
Choose to reserve and pick up the part from a local store, or request shipment of the part. Choose either the Reserve & Pickup tab or Buy It Online button. With the pick up option, verify the correct local store. Once you have selected all needed products, click on the shopping cart in the top right-hand corner. For both options, provide basic information and payment information, and place the order.
