I want to create a multi-brand website that is tabbed at the top (like Old Navy, Gap, Banana Republic, etc.) and has a single checkout? Is it possible to do so on Shopify? I will use subdomains for each of the brands in the exact same way as the Gap. [bananarepublic.gap.com, oldnavy.gap.com, athleta.gap.com]
