Where can I find an edition in English of the Commentary on Genesis by Nahmanides?

The Ramban (Nachmanides) was translated into English by Rabbi Dr. C. Chavel Major Jewish bookstores will stock them. The first link to come up on the web was: http://www.judaicapress.com/product_info.php?products_id=324&gclid=CNWNtIjItJACFQdEFQodUxGDLA
