We're setting up Magento to run 1 website and 3 stores each with 1 store view. Each store view is associated with a different domain. Since the 3 stores are part of 1 website, the catalog will be shared between the 3 stores, as well as the checkout (ie: if you add a product in store 1 you can checkout with that product in store 2). However, the look and feel of these stores is totally different.
The question I have is, since the checkout is shared, will Magento try to redirect from store 2 and 3 to store 1 to complete the checkout? Or even though the checkouts are shared, will pressing checkout on store 2 complete the checkout using store 2's domain and templates, likewise pressing checkout on store 3 will complete the checkout using store 3's domain and template?
