For me, it was a no-brainer. All my other sales at B&N, Apple, Sony, Smaswords and Kobo, combined, are less than 1% of my total sales. I jumped at the chance. The contract is only for 90 days, so it's not like I'm locked in for the copyright of my books or anything. It's 90 freaking days. You can only grow one third of a baby in that time, or shiver through one third of a winter in Wisconsin. It takes my toenail polish longer than that to grow out...okay, sorry for that detail, but I think you get my drift.
Will it work for me? I don't know. I hope so, but if nothing else, it has enabled me to schedule some free days. Before, I had to jump through hoops--backwards while juggling three bowling balls-- to get my book to go free. This is so much easier. If I did it right, my first free day should be, wait for it--no on second thought, no need to wait, No Good Deed should be free RIGHT NOW! Just for today though. I wanted to see how it would go, so I only used one of my five free days for that book.
