Using search term: 'books' as an example...
I'd go for something more like this:
(company name): promotion (ex. Free Shipping on New and Used Books)
in comparison to:
(company name): Used, New, Out-of-Print, etc.

As mentioned, it is MORE important to make your title sound attractive to potential visitors, there is no point being NO 1 for a keyword if no-one clicks on it.
Just my 2p worth
In addition, anchors to high level pages are normal 1 word or a two word keyphrase (consistent with those in the title) where lower level pages (or more focused topics) get longer anchors to match the longer titles.
