Yes, it still works. I just did it successful a few minutes ago.

I didn't find an ebook for 3 or 4 points. The sort seems to be broken, when I search for lowest priced ebooks it lists 250 before 200... and after some clicks through pages I found 150 between some 200 or 250s. Didn't want to spend more time on it and just bought one for 150pts. The ebook I bought last year for the same reason also jumped up in price, so did other 3-4 pts books that are listed in this thread.
