Where do many people buy e-books?

pu1. Personally, I like that Ridibooks are often sold cheaply as events, so if you're going to use Ridibooks, you can use an e-book terminal called Ridibook

OK

pu2. E-books are similar to regular books, and the difference is that if you buy them from one side, you have to keep going to read them, so you can use the interface between the two

OK

pu3. Whether it's Kyobo or Ridibooks, it's more important to choose one place. If you buy it here and there, you don't know where it is, so you can go in and wander around
