Is it ever too late for a PR campaign?

[Patricia]

Hello. Eighteen months ago my publisher released Communication Toolkits for Introverts. Because they came to me to write it, my expectations were as high as the sky. Needless to say, I should've gone to the pit level. After asking, prodding and even pleading for different kinds of marketing I've decided to consider personally investing in PR.

Is it ever too late to do a book trailer video, or press releases, or anything in that area?

I'm looking for feedback so that I can put the dollar to the best use of what might otherwise be average sales of a book.

Appreciate your ideas and guidance.

There is a discussion at https://www.goodreads.com/topic/show/... but it started in - 2010 - and while still going on, with 55 pages of comments, it's rather time-consuming to scroll through it to see if this question has been answered previously.
