BTT still isn't live on B&N, and when it does go live, it will also be $3.99. It's gonna stay that price. Sorry. I usually sell 1 copy of any given book for Nook, and I don't feel like going through the pricematching hassle with Amazon when it's time to jack the price back up.
If you're waiting for BTT to get up on Smashwords, that's going to take a bit. I did the majority of the formatting at various Christmas functions, and by the time I'd finished making the mobi and epub I didn't feel like making the special .doc. I felt like sipping nog and eating fire-roasted chestnuts (on a sad note, I did neither). I'll be doing that in the next few days, though. But it will likely go up at 3.99 and stay there.
