Personally, I would be inclined to use that space to "promote" more detailed inner pages which in turn, would provide the aappropriate calls to action. If done correctly - and on the assumption the site provides genuinely useful and user-appreciated information that induces people to read - I would have thought that will be far more financially beneficial not only through CTA clicks but also in developing user interaction that would assist ranking.
IMO the bottom line is that if a site is trying to issue a "Buy" directive to a user before they have digested any information, it may be sending out a signal that the site is adding little of value. A risky strategy.
