Yes, I have. I received a total of $12.74 from 10-2-2010 through 1-27-2011. I have a total of $7.18 from 1-28-2011 through 8-2-2011.
If you chose to be paid by an Amazon gift certificate you receive payment when the total reaches $10. If you chose other payment methods then you don't receive it until your total reaches $100.
