Purchasing textbooks online has become more affordable for the vast majority of students in the United States.

According to a new study, more than half of the students surveyed by the U.S. Department of Education in December 2017 purchased their textbooks online.

According the study, the average cost per unit of textbook sold online in 2017 was $1.19 per unit, with prices averaging about $1 per unit for the textbooks available in multiple formats.

According to the study by the Education Department, online textbook sales have increased more than 20% from 2014 to 2017, reaching $2.8 billion.

The number of students who purchased textbooks on the Internet grew by more than 12% from 2016 to 2017.

While the number of textbooks sold online grew by 5% between 2016 and 2017, it was still less than the number who purchased them on-campus.

However, the report also found that there were a number of reasons that students may not have purchased online textbooks.

Among the reasons, some students may have purchased textbooks as gifts or simply wanted to save money, while others may have been reluctant to purchase textbooks on-line.

Online textbook sales increased from 2012 to 2016.

The study also found there were significant increases in textbook sales between 2016 to 2018.

According for the study published by the Department of Commerce, textbook sales are now estimated to be about $9.6 billion, or 22% of the U,S.

economy.

In 2018, there were 2.2 million textbook purchases.

However, the study noted that the majority of textbook purchases were online.

The survey was conducted among 3,073 students at public, private, and nonprofit institutions in the U-S.

In the study conducted by the department of commerce, online textbooks accounted for the largest portion of total online textbook purchases, with 41% of students purchasing textbooks on a book-by-book basis, and 20% purchasing online.

The Department of Agriculture’s website and other education content platforms are also providing students with a range of educational options, including online education.

For instance, the U of T’s Learning Commons program offers students free access to all courses taught by the university’s faculty.

The Learning Commons is part of the university, and it also allows students to purchase online textbooks through their own platforms.

The online learning platform also offers access to the library system and library resources.

The United States is a leader in online textbook development, and the department is actively working to promote the use of digital textbooks in schools.

The department announced in May 2018 that it would start a new initiative that will be led by a new president who will be the first in the nation to lead the online textbook initiative.
