Are Reference Points still in business ??

Hi, everyone. I have been interested in trying some brass isolation cones for my system and decided to try the ones from Reference Points(audio) in Canada. They claim to have a superior, patented way of coupling their cones to equipment. Their website seems to be running fine but I was not able to complete self check out as my military address is not listed in their system. No phone numbers for contact either. I've sent numerous emails with a request how to complete a purchase with with zero response.
I wonder if anyone has recently bought from them. Are they in business? Thanks for your input and time.
