This was the first time I used DtiCorp.com, I found it doing research on the cost of my HVAC ebook. I added a course at the last minute and wasn't sure the price on the HVAC ebook. First I was going to purchase a used book, by the time I would have received the book, paid for the shipping and handling, I would have missed my first 2 assignments. By purchasing the eTextbook I got the book instantly and was able to complete my assignments. I enjoy using the DtiCorp.com eTextbook, because I don't have to carry the entire book around, I just print the chapters that are going to be covered during that semester; the cost of the eTextbook was in my budget, it was less expensive than going to the college bookstore and standing in the long lines. I recommend the DtiCorp.com eTextbook.

Because I use my laptop for note-taking, it was very convenient to have my entire HVAC textbook available with a click of the mouse. Not hauling around the extra textbook made it that much easier to take my laptop. I think that online textbooks are a good, cost-effective alternative to purchasing print textbooks. I look forward to seeing the new features that will be available in the future!

In the fall of 2017 I returned to school. I purchased my textbooks on-line at amazon.com because they had lower prices than my college bookstore. After I received my textbooks and a week into the semester I discovered DtiCorp.com and decided to give it a try. I have purchased and read e-books in the past for their ease of use and their portability. I thought, if there is a time when I need portability it's now considering how heavy textbooks are these days. Since I had already purchased my textbooks for the semester, I purchased a duplicate copy of one textbook, my heaviest one, on DtiCorp.com, which gave me a unique opportunity to compare the two versions. The first thing that jumped out at me was the lower price for the DtiCorp.com book than for the exact same textbook I had just purchased. Considering the price is about half the cost of the print copy, it's a smart economic choice to make. It's also a smart environmental choice to make (no trees, paper processing, transportation, etc.) The DtiCorp.com text was also easier to handle than the unwieldy, awkward print version on the text. DtiCorp.com is a smart choice.

I needed access to a book I forgot to buy for a test coming up in three days. The library did not have a copy nor did any bookstore in the area. I wasn't going to use the book other then a couple of times after this. I needed access immediately to prepare. I searched online for the eBook desperately hoping to catch a break and did. I aced the test.

The site was a great help. It fit into my budget and to be honest I rarely ever sell my textbooks back anymore because they seem to change so quickly from year to year. How often do we really go back to refer to that material especially when much of is changing? …Keep up the good work and the affordability. What I was charged was half of what I would have had to pay.

In my experience, eTextbooks through DtiCorp.com are cheaper than purchasing a hard copy from a university's bookstore. Also virtually no paper is used in the production of an eTextbook through DtiCorp.com making them more economical and environmentally friendly, which is very important to me.

I found using DtiCorp.com was a pleasant surprise. The site is very easy to navigate and find my course to complete classwork as assigned. I liked that the price was better than the used price at the student bookstore and I didn’'t have a heavy book to carry around with me. Although, I can't sell the book back the price was still better than the hassle and discount I would have to give if I had to sell. I really enjoyed my first experience and would buy a book this way again.

Why carry around five books when you can carry around one laptop? DtiCorp.com ebooks cost less and are easier to navigate through. The money you save can be used towards helper manuals, which are also given by DtiCorp.com. I will continue to use DtiCorp.com through the rest of my education.

I am a non-traditional student working full-time. I do not always have my books with me at work. However with DtiCorp.com my ebook was available online with easy viewing while I was working. On busy mornings this really is handy, no more walking out of the door just to find that I forgot my book.

I thought that the eTextbook is way better then a regular textbook because you can type in a certain subject that you need to find and it will give you all the places in the text where it talks about that. It is a much faster way to find information then flipping through a book.

I am traveling a lot and textbooks are just too heavy to carry around. Thanks to DtiCorp.com I do not have to take my books with me anymore. I just go online at the airport, the hotel, etc and can study. Now I have more room in my luggage for souvenirs.

I really enjoyed using DtiCorp.com for my online HVAC course. It relieved the stress of carrying an extra book that is too heavy for my back. It made it easy to switch back and forth between the screens. I would recommend this method of buying a textbook for anyone who has an online class. It also allows you to take notes, highlight sections, and bookmark where you left off.

The price was wonderful, and I didn't feel like I was wasting my money on books that I would never use again once class was over. I didn'’t have to carry a heavy book with me, but still had a book at my fingertips at all times.

DtiCorp.com eTextbook replaces the traditional textbook with a digital copy, great when coupled with on-line classes. I used to have to purchase all my textbooks, with DtiCorp.com I am able to get the same textbook on the spot and save some bookshelf space.

Signing up with DtiCorp.com was easy and it gave me immediate access to my e-textbook. Not having to wait in bookstore lines was a real time-saver. I could get used to not lugging my books from class to class!

My experience with your e-Books have helped me tremendously. Where the average student taking the same course at Grand Canyon University received a B or lower, I was able to receive a 100%!! Your service provided more than just the hardbook information, it provided the means to increase the font size so as to alleviate the eye strain. The extra information and links to the publisher helped to achieve the high scores that I received. I personally feel that I would not have done as well without your services.

This was my first experience using an eTextbook. There were viewing difficulties due to databases not converting text properly in the beginning but DtiCorp.com corrected it and solved the problem in a very timely and efficient manner. Their customer service was impeccable and after that the text was very user-friendly. If I have to choose a service like this in the future I would gladly return to DtiCorp.com.

I really enjoyed the DtiCorp.com HVAC textbook. It cost me about half as much as buying a new textbook and was even cheaper than the used textbooks I could find. The highlighting and printing features were very useful. I'm not one to usually do a lot of reading on the computer but having an online textbook has been much easier in most ways.
