A new cover scan from the distributor confirms that English and Spanish are available along with bonus features. The webshop is updated.
The official release date was indeed October 7, however they probaby didn't manage to get it out everywhere by this date. My supplier hasn't got it in stock yet.
For a clue on why PayPal isn't supported:
http://www.paypalsucks.com/. Anyway, regular credit/ debit card payments are really the safest way to make payments online. The Swedish payment service Payson is available for those who'd rather go through a 3rdparty. Bank transfer and international cheques are also supported.
