you get 1000 pts (+500) to spend on the site. Some manga chapters are like 98 pts, some volumes 1100. I guess each month I will get 1000 pts + 50pts. A decent amount for series that will stand no chance of ever releasing.
I agree with the idea that this a GREAT way to release many manga that would not be strong enough for a physical release, also it makes a great opportunity to simulcast manga... however it is to expensive, and the previews need to be longer.
