How legitimate and secure is One Stop Digital?

I want to buy the Nikon D3100 from the website, as it is the best deal I have seen for it. The only problem is that with a deal like that, these sites sometimes turn out to be too good to be true. I've been on a few forums but people that say it is/is not secure don't seem that reliable. Although the website looks and seems secure, I want a garuntee that they aren't going to mess me around. Any knowledge about this website and it's conduct?

Here's the link

Install the WOT add-on into your browser, it gives safety ratings for sites, and search engine returns.
Faster, and easier than asking questions in forums.
Do not trust/buy from a site unless WOT gives it a GREEN rating… If not GREEN then do not trust/buy from…
