I've put Alibaba "verified" links up in the Retina 5K and Retina 6K WikiPosts. That's the closest one can get to buying direct. You can also see Click Clack is selling at close to wholesale - I think both are good options.If you are worried about buying a monitor from a "scam" website, there is an option to buy Kuycon monitors from a number of resellers on AliExpress. The prices are more or less similar, but a big advantage is that AliExpress offers buyer protection. I have very rarely had any problems with buying there, but when there were problems I always got my money back without any problems.
I will definitely buy at least one monitor, but I'm still considering which route is the safest and most affordable.
I'm working on adding Taobao right now, there is an "official Kuycon monitor store" [kuycon显示器官方店] -- here is a test of the direct link:
