You'll find mostly American and British literature aka classic books by female writers. They also have ebooks for sell in their Ebook Store.
As the title suggest, these are classics that are under 3 or more dollars and there are a lot of familiar titles.
These are mostly romances which I really don't care to read but maybe you'll find something you might like.
I didn't try this site since you have to sign up to get the books but they seem to have a wide selection if you care to spend time browsing.
Basically they list books that might be free or on sale for a limited time and you go to the links to get the books so it's listings rather actual books. I just go here to browse what's on sale.
They have a wide selection of indie ebooks which can mean authors you have never heard of but it's worth it to browse if you are interested in finding new authors.
So many books, so many ways to browse but hey, it's free so you should do the work if you really want to read. They have a lot of classic titles. Browse the Top 100 list (link here) if you don't know where to start.
If you have a place where you go for free or low price ebooks, do share the link in the comments.
