What Are key3man Industries? Park Lane Services currently sells items on ebay.com, amazon.com, and craigslist.org under the handle of key3man. (We anticipate selling from this website in the future.) In addition to selling items for ourselves, we sell items for our clients. Our services include listing, receiving payment, packaging, and shipping. Clients remain anonymous throughout the process and pay us a negotiated fee that is a percentage of the sales, a flat rate, or a combination of the two. If we can be of service to you, please feel free to send us an email and we will get back to you shortly, or just give us a call. We look forward to working with you!
