It is so huge and vast one cannot precisely perfect it. However certain benefits could be pointed at. International edition of textbooks are simply textbooks that are published outside the United States of America. Such books are not sold in US.
However these international textbooks have all the contents similar to that of an US edition. The only difference is that these books come in paperback cover and they are sold at half the rate than the US edition. The only problem is that they are from overseas and hence shipped or couriered through flights and it might take up to two weeks to be delivered. Thus when placing orders for these books see to that you do it at the earliest before your college semester begins.
While starting college and if you are student managing independently, it is very important that you manage your expenses pretty well. Most students end up paying tuition fees, boarding fees other fees related to miscellaneous and at the end of the day, hardly saving any money. This leads to a lot of financial crisis and if you are about to spend extra for your syllabus books it is certainly next to impossible. International textbooks are the same as the books you find in any bookstore, however its price is reduced to half and serves your purposes in several ways. It is sold at such rate mainly because it is of a soft cover and not printed in color.
There are a lot of websites online which sells several books related to education on very good deals. On season sales and other offer discounts are leveraged on these books. Medical books which are normally pretty expensive are drastically reduced. However the websites are never completely reliable. There are some sellers who are allowed to sell books online and they are not educated enough. Thus their service is horrible and books you receive may also be damaged. Besides shipping these books might end up taking months. So do a thorough research from whom you are buying before placing the order.
One of the biggest benefits of buying these international editions online from a reliable website is buying it in bulk. Apart from getting up to 50% on these books, if a group of students join together and place a bulk order, the amount is reduced significantly. This is mainly because shipping charges are the most when it comes to delivering these orders to their respective owners and if you combine the order of several students to one locality, say a group of hostel students, the total expense of the order drops significantly.
