You may have overlooked that it is not necessarily a list to begin with. It could be simply noun phrases in apposition. Apposition is the use of a grammatically unnecessary noun phrase called an appositive phrase to describe the preceding noun phrase. To illustrate apposition, here are some examples with the appositive phrase in bold:
I visited Canada, a beautiful country. (from Wikipedia)
You are better than anyone, anyone I've ever met. (from Wikipedia)
But it is a trap, a clever trick by someone who is trying to get as much information about you as possible without you noticing. (from http://think-smarter.blogspot.sg/2009_01_01_archive.html)
In fact, just like the last example above, in the very text you quote:
A book makes the perfect gift, the perfect giveaway, the perfect method of saying, "Consider the following..."
apposition is the intended meaning, and it would be incorrect to insert "and" or "or" because "the perfect giveaway" and "the perfect method of saying ..." both describe "the perfect gift" and are not separate from it.
