Hi there. The main question is: what is your typical delivery time via Regular AirMail? I've ordered an RDA on FastTech on october 15th, on 18th it was sent. For now I'm waiting for 35 days (25 business days), and still haven't any messages from my mail service. In the support I've got a next message: "the estimated delivery time is up to 30 working days". So there's only 1 week left before I will try again to contact them about where is my order.
