Hello boller,
Thank you very much for your interest in Mount&Blade. You can order directly by sending US$ 22 for each serial key to
[email protected] (using send money option of your PayPal account.) However, we'll be on holiday until October 8th and we have no way of sending you the keys until that time. Therefore please place your orders after that date, ıf you'd like to use that option. I am very sorry for this inconveneince. (Alternatively clearing the cache of your browser may fix the PayPal option of the existing online seller.)
Best regards,
-Armagan
