Question about ordering on AP San Francisco

Hello, EGL! I have a quick question about ordering through the AP San Francisco website. The ordering process went well up until I got to the Payment Information page. There is no paypal option, and it doesn't appear to be secure. I say this because the website doesn't start with https like most secure pages do and it doesn't state that it is secure or encrypted. I don't feel comfortable putting in my credit card info on a page that appears to be completely unsecured and anyone could gain access to my information. Does anyone know if there actually is encryption of some sort and it isn't stated, or anything of that nature that would mean for a safer purchasing process? Any help would be appreciated.
