Smashwords is so much better. You get paid after just $10, and into a Paypal account. I sell a lot more books on Amazon than I do from Smashwords, but if I count my earnings when it arrives in my account, then I have only had from Amazon what my first publisher sent on.
So from now on, I am going to use Smashwords as the first choice to buy from, and and I'd really like as many as possible to do the same. I'm tired of earning money that I never see.
My books on Smashwords:
The threee books of the Shuki Series
and the two (so far) Penwinnard Stories.
