Although i have been selling on Amazon for a couple years now, this was the first season as a seller on FBA (stored and shipped by Amazon). And although it is still a few days from Christmas, I can safely say:
SALES WERE GREAT!
Most products seemed to get in a few extra sales that were not big movers, but far and away the most popular item I had on offer were my Scottish socks.
I have to say, I am a bit surprised at how well they have performed. They were not very popular when I had them available at first. Then I shipped a few pair into Amazon for them to sell, and it has steadily increased. Happy to see it.
