SAO is yet to have Official English translations. If you REALLY want to read an english version, I suggest just reading the online Fan Translations.

However, if you're set on a physical copy of the English translations, there aren't any at the moment. Yen Press has recently liscenced Sword Art Online, and the first Volume is scheduled for early 2014.. Volume 5-13? You're going to be doing a lot of waiting...
