If you're talking from the customer side then yeah you're right, it's only relevant to a customer whether something has a sell/rent offer attached to it. If you're talking from the supplier side then the second meaning is also relevant, firstly whether something is fit or suitable for sale/rent, then secondly whether the supplier decides to attach one or more sell/rent offers. Publishers are generally suppliers right?
