RFQ Details

I want to buy this rf receiver from this website below, but I'm having a hard time contacting them since their company is based in china and I live in the United States. I have sent them numerous emails about my request for this product and have yet to receive a email back regarding how to buy them. If you know a website or a wholesale company that sells them please contact me asap.
