I received a Historical Report from Amazon. This totals all sales of my e-books since 2011.
Figures for paperbacks are not included
Total sales 982
Free ebooks 9007
Income over that period
USA 297 dollars
UK £178
There are also figures for
Euros 16
Yen 70
Rupees 41
Canadian Dollars 1.78
Brazilian Reals 9
Nothing from Mexico
Nothing from Australia
So the only sense in which I am a best-seller would be "Best-selling book about a French Bulldog who goes into Space" or "Best selling book about a detective agency in Durrington"
