From this we can see that their contact info doesn't match up and their site is less than 2 years old. I would be extremely cautious if you decide to purchase from them. Try to find out some more info on them especially from people who have dealt with them. If you do decide to buy their products do a small sample order first to determine whether or not they are trustworthy and what their shipping, customer service and product quality is like.
All the best :)
