Fedele, there are many copies available ranging in price from $3.95 on up to over $20.00.A lot of places will allow you to pay through a PayPal Account, which is easy to set up.
If you don't want to do that, I would be more than happy to purchase a copy for you and send it over. Please just let me know how much you want to spend, whether you want paperback or hardback, etc. For a good idea of what is available go to Amazon.com or, Bookfinder.com and do a search on that title.
Hope that helps,
kat
