I’m not as long here as many others but for me it was May last year.
All time best for me was March last year.
Number of sales or earnings?
Till date December is the best for me
March 2012. – my the best month in number of sales.
November 2012. – my the best month in earnings.
January 2013. started very good.
Edit: November 2012. was the best in earning from deposits too.
February 2012 – 1 place. March 2012 – 2 place.
November 2012. – my best month in number of sales. December 2012. – my the best month in earnings.
