Is Barnes & Noble in trouble?

I can't help but wonder if Barnes & Noble is in financial trouble. I've been a "member" for a while now, and when I used to receive an email once a week I thought we had a reasonable, casual relationship. But over the last few weeks B&N has turned into a stalker, sending me at least one email message every day, with each message sounding more and more desperate: "We'll give you 10% off", "Make that 20%", "No, wait, 40% off".

Is this some form of holiday guerrilla marketing, or does B&N sound a lot like a desperate financial institution or a Big 3 auto maker?
