Anyone actually manage to redeem these points?

I have over 1,000 pts and nothing.  I have sent them two messages through their contact me link and no answer. 

I don't have any idea about the points.

But I do wonder where they get the "Each ebook is free for 1 day only" part from?

The books I've seen listed there are also on the freereadfeed.com site, and these books are usually free for quite a while.

Now, some authors or publishers might have a deal or offer freebies for a single day. (Or only a few hours, or until X number of books have been given.) That would be worth signing up for. But not for just the regular freebies listed at other places.
