Learn Braille: Uncontracted (Grade 1) & Contracted (Grade 2)

The book does a pretty good job at helping us get started with Braille. But for the amount you're paying, I just think it's better to download a PDF online.I thought since the cost is this high, the book will have some kind of engravings or some kind of marks on the sheet. But there's nothing. I still am not sure why the cost is this high. Just wanted y'all to know this, in case you were expecting any engravings inside the pages.
