Can't say. I just started selling in March. I can say that I sell on B&N much better than on Amazon. I have heard that other authors mention that March sales are way down, especially the past ten days or so.
Maybe everyone has stocked their devices full over the holidays and the past couple of months and are just trying to get through their reading lists?
I was doing okay in early March and then sales tanked. One thing a little strange is that even some of my free short stories I have on Smashwords (and B & N) are going slow in the last week or so. I'm not sure if people just overloaded their Christmas present e-readers with more books than they can read for a few months or what. Hopefully things will pick up soon.

I was wondering the same thing about Pub It. My sales are down 40% on BN Pubit this month and ironically are up 50% on Kindle, so it will even out.
