I would be kinda sceptical about using them as a 'whois check' shows they have only been listed for 3 months. They claim on the home page to accept paypal, but when you go to the 'payment details' page it only shows western union and money gram. You don't want to use either of those to purchase anything on the web..
Another red flag is that all of their contact email is yahoo and msn which are free mail providers..Thats not a good sign either..
I would suggest to stay away from them for now..
