I’ve noticed the same. Sales are normal, but none of them come from the US.
I just came across to this other post:
Unfortunately, due to some technical difficulties no one in the USA could purchase our “Creative Bundle”
Would be great to know if other Authors are getting US sales or not.
I didn’t had sale from US today. Maybe some technical problem which no one in the USA could purchase the items.
0 sales yesterday. But got 3 sales today. 2 sales from US.
So 3 sales only, all from the UK >.>
Sales are terrible these past 5 days. Hope it gets better.
Anyone else getting 0 sales from america??
I was thinking because Revostock is down, that we all have better sales, but nothing 
Same here. Sales plummet in December.
My sales have been about normal for December, maybe a bit higher, although strangely I didn’t notice any dip in sales over the weekend when I normally would. Maybe more people are working over the weekends to get everything wrapped up prior to the holidays. Who knows!
Agree. Whilst sales have been slowing down for me (naturally, given the holiday season), the weekend was surprisingly prosperous!
Yep! Zero sales for the last 8 days from America. It’s not normal.
Is there any problems? Can someone from the staff clarify this situation?
I had several sales from USA. So there is no such a problem as I think.
Back to the topic, this December is going to be my best month in here
weekends are better for a few weeks, before they used to be really dead …
Fabulous start for December, Hope this will continue for remaining days, Wish you all the same
happy for you 
that’s what i wish to all authors
It’s really really bad at the moment!
All Lul. … what’s wrong seriously
Ha yep no sales for 3 days maybe everyone is poor after xmas !
I just had a sale, can’t believe it
Same here; I have several ecommerce stores and I am noticing the exact same - sales dropped drastically around the end of November. I went searching Google for “my sales down December 2015” and there are threads with similar stats everywhere- Ebay sellers saying the same, Amazon sellers saying the same, etc.
It looks to me like the economy troubles are hitting us hard, no matter where we are selling!
