I'm very sorry for the delay, I'm having problem on where i can upload my files so that it will not be copy by other user that didn't bought it. I have now all the Files including all the photo of the Front Page of the books. I don't have any idea too about the initial price of each E-file books. I hope someone will suggest me regarding my queries. Thanks
i suggest to use a google drive for online storage for your file. Set a password for it and gave the password for those who purchased your e-files.
About the price, For me it is better to set the initial price to 50% lower the original price but it is up to you. Just giving you a guideline!
