It it a real company? I couldn't find a business address (could be a PO box) on the site. .
When I was first starting out, I was working from my home. I did not bother to register my business at first because I was still trying to feel the market and decide if this was really something that I wanted to do full-time. So I did not have a business address listed on my website for a period of time. That did not mean I was not a legitimate company. It only meant that I was in between testing the waters and registering my business. The minute I decided that this was it for me, I immediately registered my business and posted my home address as my business location. I can understand why a business would not use an address at once, but I would question any business that, after a period of time, never registered an actual address or, decided to use a P.O Box instead.
