Avon has discounted several of Margaret Moore’s books to 0.99. US only, unfortunately. For me the price was 3.50. Still a good price, though.
Beth Kery offers a novel for free at Smashwords, I have heard good things about her writing, so I intend to download it later.
Several of Gena Showalter’s early books are available for 3.50 on Books on board.
If you have the time, it might be worth browsing the discountable titles, since there are really good prices at Books on Board now.
Oh. Yes. Samhain offers a free pre-order of Just the way I like it by Erin Nicholas. No idea if the book is good, or what it is about, or how long it is. Think it is a steamy novel, though.
