Like I said, you’re changing the goalposts. Your post claimed it was $1200, so I called you on that, and that's when you shifted your argument. Anyhow, I went back to your original post and saw the link, here:
https://kuycon.us/monitors/G27P
Unfortunately, that is not actually Kuycon's website. It's a website operated by a third party, with no affiliation to Kuycon. Kuycon operates out of China and sells direct (the link I provided), or through ClickClack or Amazon. I'm not sure what that website you linked is doing, but it sounds like they could just be buying Kuycons at full price and reselling them.
ClickClack.io is the exclusive authorized international retailer of Kuycon products (excluding Russia). Full manufacturer warranty & shipping protection.
clickclack.io
ClickClack charges US$849 for the monitor, and $89 shipping, for a total of US$938, but as mentioned, it's cheaper if you just purchase direct from the manufacturer. AFAIK, ClickClack just drop ships from them anyway. As for the shipping price direct from the manufacturer, it varies from day to day. The manufacturer often sells in bulk, but from individual users who have dealt with them, it seems for single users they don't negotiate much on the unit price, but will sometimes throw in reduced or free shipping if you contact them directly and ask.
And BTW, I'll reiterate again, I didn't even buy one of these. I bought an LG UltraFine 6K. I'm just pointing out that your original $1200 price claim was simply wrong. Whether a professional would buy this or not even at a lower price is a completely different argument.
Uh, wut?!? Maybe you mean they won't use no-name brands like the Kuycon, but that's a different argument. It would be strange to claim that all professional Mac users only ever use Apple displays.
