Crate Program

One of our most popular options, the Crate Program provides the easiest way to sell your surplus parts. All you have to do is send us a general description of what you’re selling, request a crate (or more) and fill it up. From there, you’ll coordinate with our logistics team to deliver it back to us. We’ll evaluate your inventory and make you an offer!
