You submit a form.
Which form depends on which tier. The Signature catalog has an inquiry form on each build page (size, finish, contact). The DIY page is a direct order. Semi-Custom prices the build live on the page, then routes you to request it. Custom Elite uses the order form too: tell us about your project, and we send you a link to book your design consult with Sam.
Every submission goes to our team. None of them sit in a queue. None of them get auto-replied to with a "we'll be in touch" message and forgotten. Every one is read within one business day.
