Probably not - you'll more than likely just be flushing your money down the toilet.  99% of places that only accept payment in BTC and have no track record or contact information are going to be scams.  You can buy from Chinese dealers on Alibaba and use their Trade Assurance (escrow) service, and get the same or better pricing - and not have to worry about them running off with your money.  I do all of my overseas ordering through them, unless I'm dealing with the manufacturer directly - super easy to do and makes sure you're covered.
