My online bookstore, Bretsuki's Books, at amazon.com marketplace has been pretty successful. Turning over sevel hundred books in the first six months of business and the business is still growing.
I have also been continuing to create products for my zazzle.com stores. The biggest of these stores, *, has increased sales over 250% in the last year, March 1, 2013 until March 1, 2014.
My biggest surprise with my zazzle.com stores is the numbers of International sales. a full 60% of my sales in the last seven months have been from Europe, mostly Germany and closely followed by the United Kingdom.
The major seller has been with items using products bearing what you may consider United States icons, the U.S. flag and Uncle Sam have been very popular.
