1: If you aren't deliberately trying to break a convention with your design, then use it to your advantage. Since it is most common to put it bottom right, that is the first place people will go looking for it.
2: Don't group "live chat support" and "feedback" with "deals". Deals are sales related, the other two are about communicating with the business.
Since it is fixed, reappearing on scroll, people WILL see it because it effectively "blinks" at you, but that is also very distracting.
Why not replace the bottom right "feedback" with "live chat"?
I would put the feedback request at the very end of a transaction, where people will actually have something to say about the experience, and where it seems natural and optional.
