Sublime has good price and good quality. Emanga has a lot of collection. Renta also has many good choices and you can buy manga partially per chapter. Other option, you can also buy from google playbook, kindle, and kobo.
I want to buy some yaoi ebooks. I heard that English version was uncencored. But I have never bought it before. Can you suggest me some good websites to buy it?
