here on Amazon US and
here on Amazon UK. On the Direct publishing page, I'm not sure exactly what it says, since there's two rows of details, which is confusing, but here it is.
Royalty Rate Delivery Costs Estimated Royalty
35% n/a $1.05
70% $0.07 $2.04
The US dollars price is set to 2.99, and I've selected '70% royalty rate', so now that I think about it, I guess only one of those rows applies to me.
