First of all, even if you really don't have access to a phone right now, I'm pretty sure this isn't so important that you can't wait to order it by calling them when you do get access to a phone.
Secondly, after about 2 seconds of searching, one can find the "Contact Us" link on that site that Ral Partha linked to. While it does infact not explicitly list an e-mail, there's a form to fill out that you can use to contact them without a phone.
You wont last long on this site if you don't at least put in some effort...
