Heraklion Press has marked down a sizable number of their ebooks to the price of
$0.00. There are some repeats from previous sales. It seems that most of the ebooks are fiction this time, so I'm posting the information about the sale on this fiction thread.
Heraklion is, as you may know, one of the plethora of publishers of public domain ebooks which have been "cleaned up" before they have been republished.
Here is
a link to their ebooks, sorted by price low to high. A couple of books from other sources have somehow gotten into the results; they are easy to spot, however. And, who knows, you may want to own one or more of those, too.
