Can I replace the first version of the book by the latest copy?

**ysaito** · April 27, 2015, 4:56am

HI, I purchased this book on Amazon in Dec. 2012 and the book I have has deprecated chapters in it such as intractability and discrete math. To get the latest version of the book, do I need re-purchase another one? Or since I have used my book with a book cover and the condition is almost as good as new one, could I send the book by, say UPS, and have it replaced by the latest one with some extra charge?

Thanks.

Hi,

To get the latest version, you need to purchase the latest version from Amazon (paperback) or Google Play (ebook). The reason we don’t provide replacement is because EPI does not published by a publisher so we don’t have warehouse or anything like that to hoard those old copies. Thanks for your support, and please let us know if you have any problem.
