Legitimate Wholesale trade in Indonesia?

Hi, I am looking at making a purchase from an indonesian company, but am wondering if there is anyway to check the legitimacy of their business first. The company name is center-digital. They accept payment via paypal, as well as TT, and Western Union (which I'm staying clear of). They seem fairly on the level, but some of the proces seem to good to be true, so obviously am wary. Any tips? Any way to find out some more info on them? Thanks.
