I presume that I can have multiple sites, for the price of just one site, if my web site (e.g. the Orchard CMS) is capable of multi-tenancy? In this case, to make this happen, I presume I simply take advantage of the "unlimited domains" deal. Yes? My multi-tenancy solution would use only a single database (which is all you get with a one-site account). Otherwise, if I don't use the multi-tenancy feature of my chosen CMS platform - then I presume I must simply buy an additional site for each site I add, correct?
