Hmm that's interesting. Probably because amazon is a bit saturated/competitive depending on the niche you are in.
(I have some experience with ecommerce but never launched an ebook. It's probably not easy to get the ball rolling. )
Do i have to buy the book on google play to give a review? I can give you one if you want. But what text should i put in?
If you have some inspiration, let me know: nielsagaert at hotmail dot com
I have a good google account.
I can also do bol.com if you want i have an account there.
And i can also do amazon but if i won't buy the book the review will not be as valuable.
Sent me the texts you want to have
