Even though Donna Fletcher's doesn't have a coupon she is running a 99 cent special on her paranormal historical title Whispers on the Wind. Which is a backlist title. She is a very well known historical romance author.
I have no problem paying $2.99 or even $3.99 for a previously published booked. I bought alot at the regular price these past few days and I am always more inclined to buy from an author who gives away freebies. Several Kindle freebies I have bought the series to or sequels because I found I like that author's style. Lori Handeland I will buy from once she adds more of her old westerns. I'm not into her paranormal books. I do read paranormals but I read the lighthearted kind.
Marsha Canham is amazing! So be sure to pick up her freebie and her other backlist is reasonably priced.
Smashwords now has a way to sort by coupon type! Still some authors are using any coupon to giveaway their book so you have to sort through them all but it does help some.
