If you wish to connect with a seller before purchasing, you can send them a message via the Message Seller button on each product page or seller page. You will be asked to provide your name and email address, in addition to your question. Your message will be sent directly to the seller, so they will be able to respond as soon as they view it.
You will be notified via email when the seller responds to your message. You can also view any conversations you have with sellers at the Inquiries page in your Account Dashboard.
