Some salvage yards offer nationwide shipping, but the majority only will ship used parts to customers with local addresses. The best idea is to determine what salvage yards are closest to you.
Online stores like Mazda Nissan Heaven sell used salvage parts online via an eBay webstore, where customers can choose from used parts available at that given moment. The inventory often changes as the parts as sold, so it's important to check the site's current listings frequently. Purchases made through eBay transactions are eligible for national shipping, but many salvage yards only deliver to addresses closest to the business location.
