Зашел в первый попавшийся магазин купить книгу, да-да,...

I went to the first store to buy a book, yes, yes, it’s a paper one, since it turned out to be inconvenient to work with the downloaded one) the price seemed too big. I decided to search the well-known sites of the book trade, and I did not even find it on stock. Then I found the book I needed in the http://www.libex.ru/ store-service at a price almost two times lower. I understand this is something like avito for book lovers) you can buy both new and used books, as well as sell)
