I'm just curious. Which platform do you use, and, why? I am currently using KDP because of the ease of use etc. But, I find they take a huge chunk. Something like 55%, That's high.
Someone recommended books.by. Been checking them out. However, they do not support eBooks, only paperback distribution. However, you pay a one-time fee of $99 and you keep 100% royalties and paid daily. Others recommend Ingram Spark. But, you must purchase your own ISBN.
So what is your go-to?
