Does Barnes and Noble realize the the price at Amazon is $2.25 LESS for Kate Atkinson's ebook, Life After Life? Wake up, you are pricing yourselves out of the market Barnes and Noble.
Life After Life is currently showing "Sales rank: 12", and is outselling every title on the New York Times bestseller list (well, it's about tied with Harlan Coben's Six Years). That tells me that B&N is doing darned fine at selling it at the $14.99 price, and that particular title is making B&N about twice the profit-per-sale that Amazon is getting.
Pricing for maximum profit is not the same as pricing for maximum sales volume.
